\(x^2+3x+2=x^2+x+2x+2=\left(x^2+x\right)+\left(2x+2\right)=x\left(x+1\right)+2\left(x+1\right)=\left(x+1\right)\left(x+2\right)\)
\(x^2+3x+2=x^2+x+2x+2\)
\(=x.\left(x+1\right)+2.\left(x+1\right)=\left(x+1\right)\left(x+2\right)\)
Chúc bạn học tốt!!!
\(x^2+3x+2=x^2+x+2x+2=x\left(x+1\right)+2\left(x+1\right)=\left(x+1\right)\left(x+2\right)\)
\(x^2+3x+2 =x^2+2x+x+2\)
= \(x(x+2)+(x+2) =(x+2)(x+1)\)
x2+3x+2 = x2+x+2x+2 =(x2+x)+(2x+2) =x(x+1)+2(x+1) =(x+1)(x+2)
Chúc mọi người thi vui vẻ và đạt kết quả tốt![]()
