còn lại làm đi

Bài 1:

1: =>x(2x-5)(2x+5)=0

hay \(x\in\left\{0;\dfrac{5}{2};-\dfrac{5}{2}\right\}\)

2: \(\Leftrightarrow2x^2+8x-x-4=0\)

=>(x+4)(2x-1)=0

hay \(x\in\left\{-4;\dfrac{1}{2}\right\}\)

3: \(\Leftrightarrow x^3-x-6x-6=0\)

\(\Leftrightarrow x\left(x-1\right)\left(x+1\right)-6\left(x+1\right)=0\)

\(\Leftrightarrow\left(x+1\right)\left(x^2-x-6\right)=0\)

=>(x+1)(x-3)(x+2)=0

hay \(x\in\left\{-1;3;-2\right\}\)

4: \(\Leftrightarrow3x^2-12x-5x-3x^2=-34\)

=>-17x=-34

hay x=2

5: \(\Leftrightarrow\left(4x-3\right)\left(4x-3+3x\right)=0\)

=>(4x-3)(7x-3)=0

hay \(x\in\left\{\dfrac{3}{4};\dfrac{3}{7}\right\}\)

My high school is located in a small village of a countryside; therefore it is not very big and modern. There are only about one thousand students from grade ten to twelve studying in 16 classrooms, and we have go to school at different hours in a day so there will be enough rooms. Around the school is an empty grass field which will soon be projected as a part of our school, and we hope our little sisters and brothers can have a bigger and more comfortable school to study. The gate is very old and rusty, but it can still keep the students from running outside of the school during break time. Next to the gateway is the parking lot where we park all of our bikes. There are many trees and flowers which have been planted through many generations of students, and today we still keep on planting more of them to have a greener space. Those trees bring a lot of shades to us, which also provide us an ideal playground on break time and after school. There is a small soccer field in the corner, and most of the time the boys have to fight in order to play on it. We do not have a room specialized for studying sports, so we spend our Physical education class right on the school yard. The walls are painted in a light yellow color, but some parts of them had become flaked off due to the impact of time. Despite being old, my school is always clean and tidy thanks to the effort of both students and teachers. We try our best to keep the school as a healthy and friendly environment for everyone. It is not the best school someone can find, but it is still the beloved place for many generations of students include me.
