化简：3x^2-[5xy-(x^y-3xy)+4x^2y-8xy] 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) 计算：（1）8x^2y^2*(-3x/4y^5) (2)(x+y)^2/xy-y^2*(y-x)^2/xy+y^2 因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y) x平方-2xy-3y平方+8y-4 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, （12x^2y-8xy^2+16xy）/-3x+2y-4=? (12x^2y-8xy^2+16xy）/-3x+2y-4=? -4x²y-8xy²+2x²y-3xy² -4x²y-8xy²+2x²y-3xy² （5x-4y-3xy）+（8x+y-2xy)合并同类项 已知x-y=8 xy=7,则3xy-2x+2y+4(y-x)²=? 因式分解：3x^2y+6xy-4x-8 因式分解 3x^2-6xy-4x+8y 已知xy/x+y=2,求代数式8x-5xy+8y/-x+3xy-y的值
