在x^2+2xy-y^2,-x^2-y^2+2xy,x^2+xy+y^2,4x^2+1+4x中,能用完全平方公式分解因式的有几个?
在x^2+2xy-y^2,-x^2-y^2+2xy,x^2+xy+y^2,4x^2+1+4x中,能用完全平方公式分解因式的有几个?
在x^2+2xy-y^2,-x^2-y^2+2xy,x^2+xy+y^2,4x^2+1+4x中,能用完全平方公式分解因式的有几个?
有两个,-x^2-y^2+2xy,4x^2+1+4x
(-x-y)(x^2+xy+y^2)
化简x^-y^/x^-2xy+y^
2*(x-y)²(y-x)(xy)
(x^2+xy/x-y)/(xy/x-y)计算
X-Y/2X+2Y XY/X+Y²
因式分解:x×x-xy-2y×y-x-y
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+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
x^2-xy/xy-y^2约分
(y/(x^2-xy)+x/(y^2-xy))除以(x-y)/(xy)
(x+y)(x+y+2xy)+(xy+1)(xy-1)(x+y)(x-y)+4(y-1)
x^2y-2xy+y化简
X^Y-2XY^2+y^3
x-y/xy-y^2计算
