(2x-1)²(3x+2)+(2x-1)(3x+2)²-x(1-2x)(3x+2)
=(2x-1)(3x+2)(2x-1+3x+2+x)
=(2x-1)(3x+2)(6x+1)
土豆团邵文潮为您答疑解难.
如果本题有什么不明白可以追问,

(2x-1)²(3x+2)+(2x+1)(3x+2)²-x(1-2x)(3x+2)
=(3x+2)[(2x-1)²+(2x+1)(3x+2)+x(2x-1)]
=(3x+2)(4x²-4x+1+6x²+4x+3x+2+2x²-x)
=(3x+2)(12x²+2x+3)

(2 x - 1)²(3 x + 2)+ (2 x + 1)(3 x + 2)² - x(1 - 2 x)(3 x + 2)
= (3 x + 2)【(2 x - 1)² + x(2 x - 1)】+ (2 x + 1)(3 x + 2)²
= (3 x + 2)(2 x - 1)(2 x - 1 + x)+ (2 x + 1)(3 x + ...

全部展开

(2 x - 1)²(3 x + 2)+ (2 x + 1)(3 x + 2)² - x(1 - 2 x)(3 x + 2)
= (3 x + 2)【(2 x - 1)² + x(2 x - 1)】+ (2 x + 1)(3 x + 2)²
= (3 x + 2)(2 x - 1)(2 x - 1 + x)+ (2 x + 1)(3 x + 2)²
= (3 x + 2)(2 x - 1)【(3 x - 1)+ (3 x + 2)】
= (3 x + 2)(2 x - 1)(6 x + 1)
