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)
(12x^2y-8xy^2+16xy)/-3x+2y-4=?
(12x^2y-8xy^2+16xy)/-3x+2y-4=?
诺x+y=6,xy=4 求(5x-4y-3xy)-(8x-y+2xy)
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)
因式分解 x-xy+3y-3x 2x+xy-y-4x+5y-6
【x-y-(x-y分之4y平方)】【x+y-(x+y分之4x平方)】除以【3(x+y)-x-y分之8xy】
x^+2xy+y^+4=16 x^-2xy+y^=16 求(3xy+6y^)+|x^-(2xy+2y^-3x^)|的值
计算:(1)8x^2y^2*(-3x/4y^5) (2)(x+y)^2/xy-y^2*(y-x)^2/xy+y^2
化简2(x²y+xy)-3(x²y-xy)-4x²y
化简3(x²y+xy)-4(x²y-xy)-5x²y,
x平方-2xy-3y平方+8y-4
(-3x^y+2xy)-( )=4x^+xy
3(x-y)²-7(x-y)+8(x-y)²+6(x-y)求详细过程(2) 5xy-4x²y-8xy²+3xy-xy²+4x²y
x*x-xy=-3,2xy-y*y=-8,求2x*x-4xy+y*y的值
(x-y-x+y/4y^2)(x+y-x+y/4x^2)/(3(x+y)-x-y/8xy)拜托各位大神(x-y-x+y/4y^2)(x+y-x+y/4x^2)/(3(x+y)-x-y/8xy)详细,
