化简.x^2-3xy/x^2-6xy+9y^2
化简.x^2-3xy/x^2-6xy+9y^2
化简.x^2-3xy/x^2-6xy+9y^2
x^2-3xy/x^2-6xy+9y^2
=x(x-3y)/(x-3y)^2
=x/(x-3y)
【6xy=2*x*3y
(x^2-3xy)/(x^2-6xy+9y^2)
=x(x-3y)/(x-3y)^2
=x/(x-3y)
化简.x^2-3xy/x^2-6xy+9y^2
(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=
(9x^2y-6xy^2)/3xy
3xy(x^2y-xy^2+xy)-xy^2(2x^2-6xy+2x)过程
3xy(x^2-xy^2+xy)-xy^2(2x^2-xy+2x)
化简:x-y/x+3y÷x^-y^2/x^2+6xy+9y^2-(xy/x+y)
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
2x平方-3xy+(2xy-x平方)化简!
-3(2x^2-xy)+4(x^2+xy-6)
4(x²+xy-6)-3(2x²-xy)
-3(2x²-xy)+4(x²+xy-6)
化简(3x^2-5xy)+{-x^2-[-3xy+2(x^2-xy)+y^2]}
化简:3x^2-[5xy-(x^y-3xy)+4x^2y-8xy]
化简(3X平方-5Xy)+{-X平方-[-3Xy+2(X平方-xy)
因式分解X^3-2xy+xy^2
①(9x²y-6xy²)÷3xy ②(3x²y-xy²+2分之1xy)÷(-2分之1xy)
