[6xy^2(x^2-3xy)-(-3x^2y)^3]/3x^2y^2
[6xy^2(x^2-3xy)-(-3x^2y)^3]/3x^2y^2
[6xy^2(x^2-3xy)-(-3x^2y)^3]/3x^2y^2
=(6x³y²-18x²y³+27x^6y³)÷3x²y²
=2x-6y+9x^4y
3xy(x^2-xy^2+xy)-xy^2(2x^2-xy+2x)
3xy(x^2y-xy^2+xy)-xy^2(2x^2-6xy+2x)过程
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)
4(x²+xy-6)-3(2x²-xy)
-3(2x²-xy)+4(x²+xy-6)
因式分解X^3-2xy+xy^2
2x²y-3(2xy-xy)-xy
5x^3y*(-3y)^2+(-6xy)^2*(-xy)+xy^3*(-4x^2)
因式分解3x^2-6xy+x
(x-2xy)*(-xy+2y*y)-(3x*x-2xy)(x-9xy+6y*y)答案应为-2x-x*x-3x,
化简:xy分之3x^2+2xy-xy分之2x^2-xy=
x^2-xy-6y^2+3xy+y+2
( )*3xy=6x^2y+2xy^2
因式分解:3x^2+6xy^2-12xy
(9x^2y-6xy^2)/3xy
计算:3xy(x²y-xy²+xy)-xy²(2x-xy+2x)
