x^2y^2-y^4-12xy^2+36y^2 因式分解
x^2y^2-y^4-12xy^2+36y^2 因式分解
x^2y^2-y^4-12xy^2+36y^2 因式分解
x^2y^2-y^4-12xy^2+36y^2
=y²(x²-12x+36)-y^4
=y²(x-6)²-y^4
=(xy-6y+y²)(xy-6y-y²)
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
(x+y)(x+y+2xy)+(xy+1)(xy-1)(x+y)(x-y)+4(y-1)
计算:2xy/(x+y)².(x+y)/4y
(x^2+2xy+y^2-4xy)*(x^2-2xy+y^2+4xy)
4x^2y+12xy+9y分解因式
x^2y^2-y^4-12xy^2+36y^2 因式分解
因式分解x^2y^2-y^4-12xy+36y^2,
(x^-4y^)/(x^+2xy+y^)/(x+2y)/(2x^+2xy)

因式分解 x-xy+3y-3x 2x+xy-y-4x+5y-6
(-x-y)(x^2+xy+y^2)
化简x^-y^/x^-2xy+y^
2*(x-y)²(y-x)(xy)
化简：3x^2-[5xy-(x^y-3xy)+4x^2y-8xy]
计算:4xy-(x+y)^2/xy(x+y)(x-y)÷x^2+xy-2y^2/x^2y+2xy^2
（12x^2y-8xy^2+16xy）/-3x+2y-4=?
(12x^2y-8xy^2+16xy）/-3x+2y-4=?
计算:12xy^2/(x+y) * (x^2 - y^2)/4xy
