3xy(x^2-xy^2+xy)-xy^2(2x^2-xy+2x)
因式分解X^3-2xy+xy^2
2x²y-3(2xy-xy)-xy
化简:xy分之3x^2+2xy-xy分之2x^2-xy=
3xy(x^2y-xy^2+xy)-xy^2(2x^2-6xy+2x)过程
计算:3xy(x²y-xy²+xy)-xy²(2x-xy+2x)
(-3xy+2xy)-(4xy+xy)
xy-2{xy-[3x^2y-(4xy^2+0.5xy)]+4x^2y}+6xy^2
(X-3xy+4xy-y)-[-2x-2(xy-3/2xy)-y]+6xy的过程
-3(2x^2-xy)+4(x^2+xy-6)
2(x平方-xy)-3(2x平方-3xy)
1-(3xy-x)+【-2(2x+3xy)】
计算:3xy[2xy-x(y-2)+x]
2x平方-3xy+(2xy-x平方)化简!
因式分解x^3+2xy-x-xy^2=
计算3xy[2xy-x(y-2)+x-1]
(-3x^y+2xy)-( )=4x^+xy
4(x²+xy-6)-3(2x²-xy)
