\(=x\left(2x^2+3x-2\right)=x\left(2x^2+4x-x-2\right)=x\left[2x\left(x+2\right)-\left(x+2\right)\right]=x\left(2x-1\right)\left(x+2\right)\)
2x3 + 3x2 - 2x
= x ( 2x2 + 3x - 2 )
= x ( 2\(x^2\) + 4\(x-x-2\) )
= x [ ( 2\(x^2\) + 4x ) - ( x + 2 )]
= x [ 2x ( x + 2 ) - ( x + 2 )]
= x ( 2x - 1 ) ( x + 2 )
