(x+2y)^2 - x^2 - 2xy 因式分解
(x+2y)^2 - x^2 - 2xy 因式分解
(x+2y)^2 - x^2 - 2xy 因式分解
原式=x^2+4y^2+4xy-x^2-2xy
=4y^2+2xy
=2y(2y+x)
(x^2+xy/x-y)/(xy/x-y)计算
(-x-y)(x^2+xy+y^2)
化简x^-y^/x^-2xy+y^
2*(x-y)²(y-x)(xy)
x^2-xy/xy-y^2约分
.(x+y-2)(x+y-2xy)+(xy-1)^2
(x^2-xy)y÷y-x/xy怎么做?
代数 x^-y^/ x^-(y-z)^ 除以 x^+2xy+y^/(x-y)^-z^ 乘 x^+xy-xz/x^-xy
(x+y)/x /(x-(2xy-y^2)/x) 因式分解
(xy-x²)÷(x²-2xy+y²/xy)×(x-y/x²)
x-y/x²÷x²-2xy+y²/xy*(xy-x²)
X-Y/2X+2Y XY/X+Y²
因式分解:x×x-xy-2y×y-x-y
(y/(x^2-xy)+x/(y^2-xy))除以(x-y)/(xy)
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
(x-y)[(x+y)^2-xy]+(x-y)[(x-y)^2+xy]
(x^2+2xy+y^2-4xy)*(x^2-2xy+y^2+4xy)
计算(-xy)(x+2x²y)
