多项式因式分解 1,(x-y)³-(x-y)²(x+y) 2,x(x²-xy)-(4x²-4xy) 求过程,
多项式因式分解 1,(x-y)³-(x-y)²(x+y) 2,x(x²-xy)-(4x²-4xy) 求过程,
多项式因式分解 1,(x-y)³-(x-y)²(x+y) 2,x(x²-xy)-(4x²-4xy) 求过程,
1,(x-y)³-(x-y)²(x+y)
=(x-y)²(x-y-x-y)
=-2y(x-y)²
2,x(x²-xy)-(4x²-4xy)
=x²(x-y)-4x(x-y)
=x(x-y)(x-4)
(X-Y)^2(X-Y-X-Y)
=2Y(X-Y)^2
(X^2-XY)(X-4)
=X(X-4)(X-Y)
1.(x-y)²(x-y-x-y)=-2y(x-y)²过程应该看得懂吧 看不懂可以再问
2.x²(x-y)-4x(x-y)=x(x-4)(x-y)
望楼主采纳
