因式分解:(x²-x)²-4x²+4x+4因式分解:(x²-x)²-4x²+4x+4因式分解:(x²-x)²-4x

因式分解:(x²-x)²-4x²+4x+4
因式分解:(x²-x)²-4x²+4x+4

因式分解:(x²-x)²-4x²+4x+4
(x²-x)²-4x²+4x+4
=(x^2-x)^2-2(x^2-x)*2+2^2
=(x^2-x-2)^2
=(x-2)^2(x+1)^2

﹙x²-x﹚²-4x²+4x+4
=﹙x²-x﹚²-4﹙x²-x﹚+4
=﹙x²-x-2﹚²
=﹙x-2﹚²﹙x+1﹚².

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