4x*x+4xy-3y*y+2x+11y-6如何因式分解

因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y) 因式分解 x-xy+3y-3x 2x+xy-y-4x+5y-6 x²/xy-x/y 3x/4x+y - x-2y/4x+y (1-y/y+x)÷x/y²-x² 4x*x+4xy-3y*y+2x+11y-6如何因式分解 化简2(x²y+xy)-3(x²y-xy)-4x²y 计算(x^8-x^7y+x^5y^3-x^4y^4+x^3y^5-x^y^7+y^8)(x^2+xy+y^2) 计算:2xy/(x+y)².(x+y)/4y x^2-4xy+3y^2=（x-3y)(x-y)x^2-4xy+3y^2 怎么分解成（x-3y)(x-y) (x+y)(x+y+2xy)+(xy+1)(xy-1)(x+y)(x-y)+4(y-1) 化简：3x^2-[5xy-(x^y-3xy)+4x^2y-8xy] x²-y²+5x+3y+4（x+y-2xy)(x+y-z)+(xy-1）² 因式分解：x(y-3)-(2y-6) (x+y)^3-(x-y)^2(x+y) x(x^2-xy)-(4x^2-4xy) 分解公因式分解 x(y-3)-(2y-6) 2.(x+y)^3-(x-y)^2(x+y) 3.x(x^2-xy)-(4x^2-4xy) (x^-4y^)/(x^+2xy+y^)/(x+2y)/(2x^+2xy) 2x(x-y)+4xy(y-x) 因式分解2x(x-y)+4xy(y-x) 因式分解 已知x*x-4xy+4y*y=0 求[2x(x+y)-y(x+y)]/(4x*x-4xy+y*y)的值? （-3x^y+2xy)-( )=4x^+xy 因式分解x^2(x-y)-4xy(x-y)-4y^2(y-x)
