xy-[x+2y+0.5(x-4)*(y-2)]
=24
求x*y等于多少
xy-[x+2y+(0.5x-2)×(y-2)]=24
xy-[x+2y+0.5xy-x-2y+4]=24
xy-x-2y-0.5xy+x+2y-4=24
xy-0.5xy=24+4
0.5xy=28
xy=56
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
xy-2{xy-[3x^2y-(4xy^2+0.5xy)]+4x^2y}+6xy^2
(x+y)(x+y+2xy)+(xy+1)(xy-1)(x+y)(x-y)+4(y-1)
计算:2xy/(x+y)².(x+y)/4y
(x^-4y^)/(x^+2xy+y^)/(x+2y)/(2x^+2xy)
因式分解 x-xy+3y-3x 2x+xy-y-4x+5y-6
xy-[x+2y+0.5(x-4)*(y-2)]=24求x*y等于多少
2x(x-y)+4xy(y-x) 因式分解2x(x-y)+4xy(y-x) 因式分解
(x^2+2xy+y^2-4xy)*(x^2-2xy+y^2+4xy)
已知x*x-4xy+4y*y=0 求[2x(x+y)-y(x+y)]/(4x*x-4xy+y*y)的值?
化简:3x^2-[5xy-(x^y-3xy)+4x^2y-8xy]
因式分解x^2(x-y)-4xy(x-y)-4y^2(y-x)
(-x-y)(x^2+xy+y^2)
化简x^-y^/x^-2xy+y^
2*(x-y)²(y-x)(xy)
计算:4xy-(x+y)^2/xy(x+y)(x-y)÷x^2+xy-2y^2/x^2y+2xy^2
化简2(x²y+xy)-3(x²y-xy)-4x²y
(x^2+xy/x-y)/(xy/x-y)计算
