( 2x - 1 ) - x = 0

=> 2x - 1 = x

=> 2x - x = 1

=> x = 1 

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

=> \(\orbr{\begin{cases}x-1=0\\2x-3=0\end{cases}}\)=> \(\orbr{\begin{cases}x=1\\x=\frac{3}{2}\end{cases}}\)

Vậy tập nghiệm của phương trình là S = { 1 ; 3/2 }

\(\frac{x}{x+1}=\frac{x+2}{x-1}\)( đkxđ : \(x\ne\pm1\))

( Chỗ này chưa học kĩ nên chưa hiểu lắm :]

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

\(2x-x=1\)

\(x=1\)

1.

\(2n+1\) luôn lẻ \(\Rightarrow2n+1=\left(2a+1\right)^2=4a^2+4a+1\Rightarrow n=2a\left(a+1\right)\)

\(\Rightarrow n\) chẵn \(\Rightarrow n+1\) lẻ \(\Rightarrow\) là số chính phương lẻ

\(\Rightarrow n+1=\left(2b+1\right)^2=4b^2+4b+1\)

\(\Rightarrow n=4b\left(b+1\right)\)

Mà \(b\left(b+1\right)\) là tích 2 số tự nhiên liên tiếp \(\Rightarrow\) luôn chẵn

\(\Rightarrow4b\left(b+1\right)⋮8\Rightarrow n⋮8\)

Mặt khác số chính phương chia 3 chỉ có các số dư 0 và 1

Mà \(\left(n+1\right)+\left(2n+1\right)=3n+2\) chia 3 dư 2

\(\Rightarrow n+1\) và \(2n+1\) đều chia 3 dư 1

\(\Rightarrow n⋮3\)

\(\Rightarrow n⋮24\) do 3 và 8 nguyên tố cùng nhau

Bài văn bạn cần nè , tuy không hay lắm thôi nhé . bạn tự chia bố cục nha !

"Learning for each person is very important and so am I. I feel learning extends knowledge to people. During this summer, I spend most of my time studying. Every day I study mainly 4 subjects: math, literature, English and chemistry. Maths taught me about in-depth computing, opening a new level of knowledge in this area. Learning literature gives me an enjoyable life experience both in the country and in the world, allowing me to explore from the past, present to the future. Learning English helps me become good at communicating and dealing with foreigners. Learning chemistry, it tells me scientifically, tells me more about strange phenomena. All these subjects are very important to me, it is part of my dream, I value it and will try to accomplish these 4 subjects well."
