-Dạng 1: Phương trình tích.

a) \(2x\left(x+1\right)=x^2-1\)\(\Leftrightarrow2x\left(x+1\right)=\left(x-1\right)\left(x+1\right)\)

\(\Leftrightarrow2x\left(x+1\right)-\left(x-1\right)\left(x+1\right)=0\)

\(\Leftrightarrow\left(x+1\right)\left(2x-x+1\right)=0\)

\(\Leftrightarrow\left(x+1\right)\left(x+1\right)=0\)

\(\Leftrightarrow\left(x+1\right)^2=0\)

\(\Leftrightarrow x+1=0\Leftrightarrow x=-1\)

Vậy phương trình có nghiệm duy nhất : x = -1

b) \(x^3+3x^2-2x-2=0\)\(\Leftrightarrow\left(x^3-x^2\right)+\left(4x^2-4x\right)+\left(2x-2\right)=0\)

\(\Leftrightarrow x^2\left(x-1\right)+4x\left(x-1\right)+2\left(x-1\right)=0\)

\(\Leftrightarrow\left(x^2+4x+2\right)\left(x-1\right)=0\)

\(\Leftrightarrow\left[\left(x+2\right)^2-2\right]\left(x-1\right)=0\)

\(\Leftrightarrow\orbr{\begin{cases}\left(x+2\right)^2-2=0\\x-1=0\end{cases}\Leftrightarrow\orbr{\begin{cases}\left(x+2\right)^2=2\\x=1\end{cases}}}\)

Xét phương trình \(\left(x+2\right)^2=2\)

\(\Leftrightarrow\orbr{\begin{cases}x+2=\sqrt{2}\\x+2=-\sqrt{2}\end{cases}\Leftrightarrow\orbr{\begin{cases}x=\sqrt{2}-2\\x=-\sqrt{2}-2\end{cases}}}\)

Dạng 2  ; Phương trình chứa ẩn ở mẫu.

\(\frac{3}{1-5x}+\frac{5}{3-5x}=\frac{x-27}{\left(5x-1\right)\left(5x-3\right)}\left(ĐKXĐ:x\ne\frac{1}{5};x\ne\frac{3}{5}\right)\)

\(\Leftrightarrow\frac{3}{1-5x}+\frac{5}{3-5x}=\frac{x-27}{\left(1-5x\right)\left(3-5x\right)}\)(phần này bạn nhớ đọc kĩ bên vế phải)

\(\Leftrightarrow\frac{3\left(3-5x\right)}{\left(1-5x\right)\left(3-5x\right)}+\frac{5\left(1-5x\right)}{\left(3-5x\right)\left(1-5x\right)}=\frac{x-27}{\left(1-5x\right)\left(3-5x\right)}\)

TẾT XƯA (THANH TÂM)

Con cào cào giật mình nhảy tanh tách vào tháng giêng

Lũ gà con ríu rít tranh nhau chú giun mẹ gà mới mớm

Mẹ rọc lá chuối đem hong trong nắng sớm

Cha chẻ nốt đống củi đang vương vãi phía sau nhà...

 

Xuân đến dịu dàng như cách mẹ cầm tay cha

Lễ những mảnh dằm mà như nâng niu niềm hạnh phúc

Cún con ham chơi rượt đám gà xao xác

Mèo già rướn người rũ biếng lười cọ cọ gốc cau non...

 

Xuân đến rộn ràng như bầy chim nghịch ngợm ở góc vườn

Bé trai quét bồ hong bồ hóng nơi chái nhà, góc bếp

Em gái vặt lá để gốc mai điệu đà kịp thay váy vàng đón Tết

Cha dán giấy mới vào liếp phên đã cũ qua bao mưa tạt gió lùa...

 

Bụi tre già cũng theo gió xạc xào khua

Như nhắc cha dựng cây nêu để đuổi xua những điều không may mắn

Mẹ dọn cỗ cúng ông Táo ông Công với tất cả lòng thành kính

Khấn nguyện cho mọi người một năm mới được an yên...

 

Xuân đến nhẹ nhàng như đôi mắt trẻ hồn nhiên

Cứ lôi ra, cất vô chiếc áo mẹ mới mua dù thèm thuồng vẫn nén lòng để dành mặc Tết

Mẹ trải lá, nếp mới, đậu xanh, miếng thịt heo ngon để gói từng đòn bánh tét

Cha nhen bếp khói nồng cời lên mắt cay cay...

 

Lũ trẻ hứa hẹn thức đón giao thừa nhưng rồi đứa nào cũng ngủ lăn quay

Sáng mùng một bịt tai, trốn xa khi cha châm lửa vào phong pháo đỏ

Chúc mẹ chúc cha những điều tốt lành để được lì xì và hân hoan khi mình trở nên giàu có

Nhặt pháo lép xong rồi hớn hở chạy đi chơi...

 

Người lớn dẹp lo âu để gặp ai cũng mừng rỡ tươi cười

Uống tách trà thơm, ôn cố tri tân và nói nhiều về hy vọng

Bỗng thấy thương người, thương mảnh đất mình đang sống

Như tiếp thêm nghị lực, niềm tin để đi qua gian khó cuộc đời ...

Tết xưa ơi...!

Every ten minutes, one kind of animal, plant or insect dies out. for ever. If nothing is done about it, one million species that are alive today will have become extinct twenty years from now.
The seas are in danger They are being filled with poison: industrial and nuclear waste., chemical fertilisers and pesides, sewage. The Mediterranean is already nearly dead; the North Sea is following. If nothing done about it, one day soon nothing will be able to live in the seas.
The tropical rain forests, which are the origin of half the earth’s living things( including many rare animals and plants), are being destroyed. If nothing is done about it, they will have nearly disappeared in twenty years. The effect on the world’s climate – and on our agriculture and food supplies – will be disastrous.
Fortunately, somebody is trying to do something about it. In 1961, the World Wildlife Fund was founded - a small group of people who wanted to raise money to save animals and plants from extinction. Today, the World Wildlife Fund is a large international organisation. It has raised over 35 million pounds for conservation projects, and has created or given support five continents. It has helped 30 mammals and birds – including the tiger – to survive Perhaps this is not much, but it is a start. If more people give more money – and if more governments wake up to what is happening – perhaps the World Wildlife Fund will be able to help us to avoid the disaster that threatens the natural world, and all of us with it.

\(|x-1|=|x+2|\)

Nếu x>=1; ta có:

x-1= x+2 -> vô nghiệm

Nếu x<1 và x>=-2. ta có:

-x+1=x+2-> x=-1/2

Nếu x<-2; ta có

-x+1= -x-2 -> Vô nghiệm.

Vậy đáp số x=-1/2

2 tháng 3 2021

| x - 1 | = | x + 2 |

Với x < -2 pt <=> -( x - 1 ) = -( x + 2 ) <=> -x + 1 = -x - 2 ( vô nghiệm :)) )

Với -2 ≤ x < 1 pt <=> -( x - 1 ) = x + 2 <=> -x + 1 = x + 2 <=> -2x = 1 <=> x = -1/2 ( tm )

Với x ≥ 1 pt <=> x - 1 = x + 2 ( vô nghiệm :)) )

Vậy phương trình có nghiệm duy nhất x = -1/2

Nói về văn chương cổ Việt Nam, giáo sư Trần Văn Giàu có một ý kiến rất sâu sắc: “Từ thế kỉ X đến thế kỷ XV trên nền trời văn chương yêu nước Đại Việt, nổi bật lên ba tác phẩm như một cụm núi Ba Vì cao ngất, người ở xa trăm dặm, người sống sau trăm đời đều theo đó mà gióng hướng: Nam quốc sơn hà, Hịch tướng sĩ, Bình Ngô đại cáo…Mỗi áng văn một vẻ, cả ba là mẫu mực tuyệt vời ở từng giai đoạn của chủ nghĩa yêu nước truyền thống Việt Nam. Văn bản sau là một trong những đoạn hay nhất của tác phẩm Hịch tướng sĩ:

“Huống chi ta cùng các ngươi sinh phải thời loạn lạc, lớn gặp buổi gian nan. Ngó thấy sứ giặc đi lại nghênh ngang ngoài đường, uốn lưỡi cú diều mà sỉ mắng triều đình, đem thân dê chó mà bắt nạt tể phụ, thác mệnh Hốt Tất Liệt mà đòi ngọc lụa, để thỏa lòng tham không cùng, giả hiệu Vân Nam Vương mà thu bạc vàng, để vơ vét của kho có hạn. Thật khác nào như đem thịt mà nuôi hổ đói, sao cho khỏi để tai vạ về sau!

          Ta thường tới bữa quên ăn, nửa đêm vỗ gối; ruột đau như cắt, nước mắt đầm đìa;chỉ căm tức chưa xả thịt lột da, nuốt gan uống máu quân thù. Dẫu cho trăm thân này phơi ngoài nội cỏ, nghìn xác này gói trong da ngựa, ta cũng vui lòng.”

Chỉ ra nghệ thuật đặc sắc được sử dụng trong đoạn văn trên.

Dear Sir/ Madam,

I’m writing because I am at the beach with some friend last weekend and the amount of rubbish where we found there was unbelievable.

I think there are possibly two reason for this. Firstly, people aren’t responsible enough and they threw their rubbish away anywhere. Perhaps we need a few sign and people who patrol the beach. Also, there aren’t bins enough on or near the beach, so I think we need more. Secondly, nobody clean the beach. I think this is terribly in a tourist town. We need people to clean the beach and empty the bins every day.

We must definitely to do something about this situation. We must do it right away if we want a cleaner, attractiver beach.

Alan

2. Read the passage and answer these questions below. (1point)

After retiring, my uncle – a lover of the sea- took up a strange leisure activity : he spends most mornings at the beach, looking for things that the sea sends ashore. He says: It’s a multi-beneficial leisure activity. I can get some exercise, blending, picking up, and walking. I can breathe the fresh air and enjoy the vastness and quietness of the sea. Sometimes I watch the children playing beach games and I feel years younger. At the same time, I can also clean the beach. It’s volunteer work, isn’t it? Many of the things I pick up from the beach are still useful to someone. I clean them and sell them at the Sunday flea market in the town nearby. Do you know of any leisure activity that pays? Mine does!
