Question

3x²+7x+2

phân tích đa thức thành nhân tử
 

Answer 1

\(3x^2+7x+2\)

\(=3x^2+6x+x+2\)

\(=3x\left(x+2\right)+\left(x+2\right)\)

\(=\left(3x+1\right)\left(x+2\right)\)

Answer 2

\(3x^2+7x+2\)

\(=3x^2+x+6x+2\)

\(=x\left(3x+1\right)+2\left(3x+1\right)\)

\(=\left(3x+1\right).\left(x+2\right)\)
