因式分解(1+x)^3(2-3y)^2-(x+1)(3y-2)^2+(-1-x)^2(3y-2)^3
要详细步骤,谢

因式分解(1+x)^3(2-3y)^2-(x+1)(3y-2)^2+(-1-x)^2(3y-2)^3要详细步骤,谢
(1+x)^3(2-3y)^2-(x+1)(3y-2)^2+(-1-x)^2(3y-2)^3
=(x+1)^3(3y-2)^2-(x+1)(3y-2)^2+(x+1)^2(3y-2)^3
=(x+1)(3y-2)^2[(x+1)^2-1+(x+1)(3y-2)]
=(x+1)(3y-2)^2[(x^2+2x+3xy-2x+3y-2)]
=(x+1)(3y-2)^2(x^2+3xy+3y-2)

(1+x)^3(3y-2)^2-(x+1)(3y-2)^2+(1+x)^2(3y-2)^3
=(1+x)(3y-2)²×[ (1+x)²-1+(1+x)(3y-2)].
=(1+x)(3y-2)²×[1+2x+x²+3y-2+3xy-2x]
=(1+x)(3y-2)²×[x²+3y+3xy-1]
=(1+x)(3y-2)²×[(x²-1)+3y(x+1)].
=(1+x)(3y-2)²×[(x+1)(x-1+3y)].
=(1+x)²(3y-2)²(3y+x-1).
