B(14){0;+14;+28;......}

mà x là <52

<=> x ={0;+14;+28;+42}

đề:)?

mk nghĩ là 

vẳng đâu khúc nhạc tình tang tang tình

bạn ko chọn cux ko sao nha

\(x+6⋮x+2\)

\(\Leftrightarrow x+2\in\left\{1;-1;2;-2;4;-4\right\}\)

hay \(x\in\left\{-1;-3;0;-4;2;-6\right\}\)

6. Yes, it was.

7. Yes, they did.

8. Yes, I did.

9. No, they won't.

10. Yes, they will.

11. Yes, I can.

12. Yes, you can.

13. Yes, we are.

14. Yes, I am.

15. No, I weren't.

1. Yes, he is.

2. No, I'm not.

3. Yes, it does.

4. Yes, I do.

5. Yes, there was.

\(\left(x-1\right)-\left(x-1\right)^3=00\)

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

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

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

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

\(\Rightarrow\)x=1 hoặc x=0 hoặc x=2

SORRY NHA CHỖ NÀY MÌNH KO VIẾT ĐC :V

CHÚC BẠN HỌC TỐT!

\(\left(x-1\right)-\left(x-1\right)^3=0\)

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

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

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

\(\Leftrightarrow x=0;x=1;x=2\)

Vậy tập nghiệm phương trình là S = { 0 ; 1 ; 2 } 

cảm ơn nhiều ~
