Translation machines are one of the greatest inventions. First, they are very helpful for travellers because travellers can quickly translate signs, menus, and directions. This makes getting around in new places easier. Second, they help people from different countries understand each other better. This means we can share ideas and work together more easily. Third, translation machines are great tools for learning new languages. You can use them to translate words and phrases, which helps you practise and improve your language skills. In conclusion, translation machines are an amazing invention that makes travelling, communicating and learning easier.

A translation machine offers numerous advantages in our globalized world. Firstly, it provides instant communication, allowing people who speak different languages to understand each other immediately. This is incredibly useful for travelers navigating foreign countries. Secondly, it enhances efficiency in business and education by translating documents or lectures quickly. Instead of spending hours with a dictionary, users can get results in seconds. Furthermore, modern devices are portable and user-friendly, making them accessible to everyone. In conclusion, translation machines are essential tools that bridge cultural gaps and make the world feel more connected.

1 During the flood, you should listen to the instructions from local authorities

2 Mars is one of the most promising planets for life in solar system

Q1: During the flood,you should listen to the instructions of the local authorities.

Q2: Mars is one of the most promising planets for life in the solar system.

ĐKXĐ: \(x\ne\left\{-1;0;1\right\}\)

a.

\(A=\dfrac{x^2+1}{x}+\dfrac{\left(x-1\right)\left(x^2+x+1\right)}{x\left(x-1\right)}+\dfrac{x^4-1-x\left(x^2-1\right)}{-x\left(x^2-1\right)}\)

\(=\dfrac{x^2+1}{x}+\dfrac{x^2+x+1}{x}+\dfrac{\left(x^2-1\right)\left(x^2+1\right)-x\left(x^2-1\right)}{-x\left(x^2-1\right)}\)

\(=\dfrac{2x^2+x+2}{x}+\dfrac{\left(x^2-1\right)\left(x^2-x+1\right)}{-x\left(x^2-1\right)}\)

\(=\dfrac{2x^2+x+2}{x}-\dfrac{x^2-x+1}{x}\)

\(=\dfrac{x^2+2x+1}{x}=\dfrac{\left(x+1\right)^2}{x}\)

b.

\(x^2+x=12\Leftrightarrow x^2+x-12=0\)

\(\Leftrightarrow x^2+4x-3x-12=0\)

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

\(\Leftrightarrow\left(x-3\right)\left(x+4\right)=0\Rightarrow\left[{}\begin{matrix}x=3\\x=-4\end{matrix}\right.\)

Với \(x=3\Rightarrow A=\dfrac{\left(3+1\right)^2}{3}=\dfrac{16}{3}\)

Với \(x=-4\Rightarrow A=\dfrac{\left(-4+1\right)^2}{-4}=-\dfrac{9}{4}\)

c. Đề bài sai, \(A>4\) chỉ khi \(x>0\), còn khi \(x< 0\) thì \(A< -4\)
