(x+y)(x+y)-x(x+y)急啊啊啊啊,(x+y)(x+y)-x(x+y)急啊啊啊啊,(x+y)(x+y)-x(x+y)急啊啊啊啊,(x+y)(x+y)-x(x+y)=[(x+y)-x](x+y
(x+y)(x+y)-x(x+y)急啊啊啊啊,
(x+y)(x+y)-x(x+y)急啊啊啊啊,
(x+y)(x+y)-x(x+y)急啊啊啊啊,
(x+y)(x+y)-x(x+y)
=[(x+y)-x](x+y)
=y(x+y)
=5x*x+10x*y+5y*y-x*x-x*y=4x*x+9x*y+5y*y
话说你是几年级的??
同时提取(x+y) 啊
(x+y)(x+y)-x(x+y)
=(x+y)[(x+y)-x]
=y(x+y)
(x+y)(x+y)-x(x+y)急啊啊啊啊,
因式分解(x-y)^2-(y-x)应为什么啊啊啊啊
化简,亲快啊啊急!(3x-2y)(7x-y)-(4x+3y)(x-y)
已知6x-7y=0,求,x分之y,x分之y+x,y分之x-y急啊啊啊啊啊啊啊啊啊啊啊,初二的数学,答案是:x分之y=7分之6,x分之y+x=7分之13,y分之x-y=6分之1,求过程啊 啊啊啊~~!答案是
3(x-y)^2-12(x-y)^2+9帮帮忙啊啊.我很急^O^
{(x,y) |x|+|y|
x>y?x:y
已知(5.3x+4.7y-112)²+丨4.7x+5.3y-88丨=0,求(x+3.1y)的2013次方麻烦快点,急啊啊啊啊啊啊啊啊啊啊啊啊
因式分解(x+y)(x-y)=?急
若根号(2x-y)与(x+2y-5)的绝对值互为相反数,则(x-y)的2009次方=急急急急急急明天要交作业啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊!
y=x-√1-x²的值域么偶有人做对啊啊啊啊啊啊啊啊啊啊啊啊
x^/y-x-y^/y-x化简.
化简x(y-x)-y(x-y)
行列式计算 x y x+y y x+y x x+y x y|x y x+y ||y x+y x ||x+y x y |
y/(x+y)-x/(x-y)
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
[4y(2x-y)-2x(2x-y)]/(2x-y) 急
(x+2y)(x-y)(x-2y)(x+y) 计算 急
