分解因式:x²(x-1)-2x(x²-2x+1)的分解过程
答
原式=x²(x-1)-2x(x-1)²=x(x-1)(x-2x﹢2)=x(x-1)(2-x)
答
x²(x-1)-2x(x²-2x+1)
=x²(x-1)-2x(X-1)²
=X(X-1)[x-2(x-1)]
=x(x-1)(x-2x+2)
=x(x-1)(2-x)
答
x²(x-1)-2x(x²-2x+1)=x²(x-1)-2x(x-1)²
=(x-1)(x²-2x)
=x(x-1)(x-2)
答
x²(x-1)-2x(x²-2x+1)
=x²(x-1)-2x(x-1)²
=(x-1)[x²-2x(x-1)]
=(x-1)(﹣x²+2x)
=﹣x(x-1)(x-2)
