My home village is now different from the village in my father’s story. in his story, my village is very poor.Everyone live a hard life that time. People lack of food, of money. Now, it is different. People don’t live a hard life anymore. They have enough food, enough money, everyone got a house, and many more things. The only things that doesn’t change is sentiment. Everyone always be very happy. They live together, help each other when they need, that isa luxury.That makes my village a wonderful place for everyone. People are just farmer, but they solidarity in the face of penury. And when they have money in their hands, they still solidarity they are friendly with others, they are helpful, they are good people. That’s about people.Landscape is still the old days. That river, that mountain. Nature is harmony with people. People live with nature, people product things of nature, and nature always open-handed with people, give them resource for themto build their house. That is what people seek, and they live with it very well.That’s all I can say about my home village, in my opinion, my village is a wonderful place. War does not determine who is right, only who is left:” Ask not what your country can do for you but what you can do for your country”.
\(=\left(\sqrt{2}x\right)^2+2\cdot\sqrt{2}x\cdot\frac{\sqrt{2}}{4}+\frac{1}{8}+\frac{7}{8}\)
\(=\left(\sqrt{2}x+\frac{\sqrt{2}}{4}\right)^2+\frac{7}{8}\)
vì \(\left(\sqrt{2}x+\frac{\sqrt{2}}{4}\right)^2>=0\)=> \(2x^2+x+1>=\frac{7}{8}\)
=> min = \(\frac{7}{8}\)
\(\left(8x-4x^2-1\right)\left(x^2+2x-1\right)=4\left(x^2+x+1\right)\)
\(11x^2+6x-4x^4-1=4x^2+4x+4\)
\(11x^2+6x-4x^4-4x^2-4x-4=0\)
\(7x^2+2x-4x^4-5=0\)
\(\left(x-1\right)\left(x-1\right)\left(-4x^2-8x-5\right)=0\)
