化简:3x^2-[5xy-(x^y-3xy)+4x^2y-8xy]
2x²y-3(2xy-xy)-xy
化简(3x^2-5xy)+{-x^2-[-3xy+2(x^2-xy)+y^2]}
x^3y(-4y)^2+(-7xy)^2*(-xy)-5xy^3*(-3x)^2
5x^3y*(-3y)^2+(-6xy)^2*(-xy)+xy^3*(-4x^2)
5x^2y/-1/2xy*3xy^2
2xy+5y^2+( )=x^2+3xy
因式分解 x-xy+3y-3x 2x+xy-y-4x+5y-6
计算:5xy^2-[3xy^2-(4xy^2-2x^2y)]+2x^2y-xy^2
5xy^2-(3xy^2-(4xy^2-2x^2y))+2x^2y-xy^2求
5xy^2-{2x^y-[3xy^2-(xy^2-2x^2y)]/(-1/2xy)}
5x^2y-3xy^2+4xy-14xy^2+4xy-2x^2y(化简)
已知x^2-xy=5,xy-y^2=-3求3(x^2-xy)-xy+y^2
2x平方y-2xy+3xy平方+5+2xy+x平方y-3xy平方-3 过程!
[5xy^2(x^2-3xy)-(-3x^2y^2)^3]/(5xy^2)
-3(xy-2x²)-[y²-(5xy-4x²)+2xy]
x^2-xy/xy-y^2约分
((xy+2)(xy-2)-2x²y²+5(xy-y)²)÷(2xy)
