你等一下啊.计算中.
给你解出一点
分号上面的那个,可以解出(X+2y)×(x+y)
下面的那个可以解成X(x+2y的2次方)
2x²y-3(2xy-xy)-xy
x^2-xy/xy-y^2约分
3xy(x^2y-xy^2+xy)-xy^2(2x^2-6xy+2x)过程
计算:3xy(x²y-xy²+xy)-xy²(2x-xy+2x)
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
计算:3xy[2xy-x(y-2)+x]
计算3xy[2xy-x(y-2)+x-1]
(-3x^y+2xy)-( )=4x^+xy
化简:3x^2-[5xy-(x^y-3xy)+4x^2y-8xy]
(x^2+xy/x-y)/(xy/x-y)计算
x^2-xy-6y^2+3xy+y+2
3xy(x^2-xy^2+xy)-xy^2(2x^2-xy+2x)
(x-2xy)*(-xy+2y*y)-(3x*x-2xy)(x-9xy+6y*y)答案应为-2x-x*x-3x,
(x^2+2xy+y^2-4xy)*(x^2-2xy+y^2+4xy)
因式分解:(2x-y)(x^2+xy-2y^2) xy(x^2-xy)(-3xy^2)
化简(3x^2-5xy)+{-x^2-[-3xy+2(x^2-xy)+y^2]}
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
