Question

Phân tích đa thức thành nhân tử :

 \(2x^2-5x+3\)

Answer 1

\(2x^2-5x+3\)

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

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

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

Answer 2

\(2x^2-5x+3=2x^2-2x-3x+3\)\(=2x\left(x-1\right)-3\left(x-1\right)=\left(2x-3\right)\left(x-1\right)\)

Answer 3

\(2x^2-5x+3\)

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

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

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