(3x²y-²)²÷(x-²y)³ 要过程,给好评.
(3x²y-²)²÷(x-²y)³ 要过程,给好评.
(x-y)² - (-y-2x)(y-2x) 要过程
(x-y)/(2x+2y)与(xy)/(x+y)²通分要过程
计算(3x-3y)²(x-y)³(y-x)²(y-x)³要过程,
[x(x²y²-xy)-y(x²-x³y)]÷3x²y
因式分解:[x(x²y²-xy)-y(x²-x³y)]÷3x²y
2.(x+y)²(x-y)²-(x-y)(x+y)(x²+y²)
求因式分解(x-y)²-2(x-y)³和(x+y)(x-y)-x(x-y)
(2x-3y)(2x+3y)(4x²+9y²)求过程
(x-y)³(x-y)²(y-x)怎么算?详细解题过程,谢谢.
因式分解 -5x³y(x-y)³+20y【x²(y-x)】²
(x-y)³(y-x)(y-x)²+(x-y)^6
