.化简什么的(x-y+4xy/x-y)(x+y-4xy/x+y)抱歉我只是懒得算了..T T
怎么化简(x-y+4xy/x-y)(x+y-4xy/x+y)(/是分数线)
谁帮我化简:[(x+y)(x-y)-(x+y)^2-2y(x-y)-2xy]÷xy
{x-y+(4xy/x-y)}{x+y-(4xy/x+y)}怎么解?
x^2y+4xy+4y
(x^-4y^)/(x^+2xy+y^)/(x+2y)/(2x^+2xy)
5xy^2-[3xy^2-(4xy^2-2x^y)]+x^2y-xy^2如何化简
xy-1+x-y
已知x*x-4xy+4y*y=0 求[2x(x+y)-y(x+y)]/(4x*x-4xy+y*y)的值?
1.化简求值:(x+y)(x-y)-(x-y)²-6x²y÷2y+(2xy)²÷(-4xy
化简求值(x+y)(x-y)-(x-y)²-6x²y/2y+(2xy)²/(-4xy)其中
化简求值(x+y)(x-y)-(x-y)²-6x²y除2y+(2xy)²除(-4xy)其中
x²/xy-x/y
