因式分解:(1).-2x(y-z)³(2).6y(x-y)²+2(y-x)³第一题改为-2x(y-z)³+4x³(z-y)³

因式分解:(1).-2x(y-z)³(2).6y(x-y)²+2(y-x)³第一题改为-2x(y-z)³+4x³(z-y)³
因式分解:(1).-2x(y-z)³(2).6y(x-y)²+2(y-x)³
第一题改为-2x(y-z)³+4x³(z-y)³

因式分解:(1).-2x(y-z)³(2).6y(x-y)²+2(y-x)³第一题改为-2x(y-z)³+4x³(z-y)³
(1).--2x(y-z)³+4x³(z-y)³=2x(z-y)³+4x³(z-y)³=2x(z-y)³(1+2x²)
(2).6y(x-y)²+2(y-x)³=6y(x-y)²-2(x-y)³=2(x-y)²[3y-(x-y)]=2(x-y)²(4y-x)

(1)题目不全
(2)6y(x-y)²+2(y-x)³
=(x-y)²(6y+2y-2x)
=2(x-y)²(2y-x)

????好难
