汗,
1.(x-4)(x-1)-1 十字交叉凑凑
3.(x^2-2x-3)(x^2-2x-4)
7.先全拆开y^2 ,-4y +4 一类
4x -2xy 一类
所以就(2-y)^2+2x(2-y)
因式分解 x-xy+3y-3x 2x+xy-y-4x+5y-6
化简:3x^2-[5xy-(x^y-3xy)+4x^2y-8xy]
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
(4x^2+5xy-7x)-(5x^2y+4xy+x)
2X^+XY-Y^-4X+5Y-6
2x^+xy-y^-4x+5y-6=?
x^3y(-4y)^2+(-7xy)^2*(-xy)-5xy^3*(-3x)^2
5x^3y*(-3y)^2+(-6xy)^2*(-xy)+xy^3*(-4x^2)
求(3x^+y^-5xy)-【2x^-(-4xy-y^+7x^)】=?
求(3x^+y^-5xy)-【2x^-(-4xy-y^+7x^)】=?
x²-y²+5x+3y+4(x+y-2xy)(x+y-z)+(xy-1)²
(x^-4y^)/(x^+2xy+y^)/(x+2y)/(2x^+2xy)
(x^2+xy/x-y)/(xy/x-y)计算
若(x*x+y*y)(x*x+y*y)-4x*x*y*y=0,求代数式(x*x+5xy+y*y)/(x*x+2xy+y*y)的值
2x(x-y)+4xy(y-x) 因式分解2x(x-y)+4xy(y-x) 因式分解
(x+y)(x+y+2xy)+(xy+1)(xy-1)(x+y)(x-y)+4(y-1)
已知x-y=3xy,求5x+2xy-5y/x-4xy-y的值
已知X+Y=2XY,求4X-5XY+4Y 除以X+XY+Y 的值
