(2x-y)^2-10(2x-y)+25因式分解(2x-y)^2-10(2x-y)+25因式分解(2x-y)^2-10(2x-y)+25因式分解(2x-y)^2-10(2x-y)+25完全平方=[(2
(2x-y)^2-10(2x-y)+25 因式分解
(2x-y)^2-10(2x-y)+25 因式分解
(2x-y)^2-10(2x-y)+25 因式分解
(2x-y)^2-10(2x-y)+25 完全平方
=[(2x-y)-5]²
=(2x-y-5)²
25(x-y)*2+10(y-x)+125（x-y)^2+10(y-x)+1
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
化简y(x+y)+(x+y)(x-y)-x^2
(x+y)(x-y)-(x-y)^2如题 (x+y)(x-y)-(x-y)^2
【2(x-y)(x-y)(x-y)-8(x-y)(x-y)(x+y)+6y(x-y)(x-y)]/2(x-y)(x-y)
因式分解x(x+y)(x-y)-x(x+y)^2
(x-y)^2+10(y-x)+25因式分解 （x-y）²-10（y-x）+25（x-y）²+10（y-x）+25只要结果
[(x-y)^2-(x+2y)(x-2y)]/y
计算:y-x分之x+y+x-y分之y-y-x分之2x-y
x^2(x-y)+(y-x)
x(x-y)2-(y-x)3
【(x-y)^2+(x+y)(x-y)】除以 2x
[(x-y)²+(x+y)(x-y)]除以2x
(2x-y)^2-10(2x-y)+25 因式分解
计算.25(x+y)^2-0.81(x-y)^20.25(x+y)^2-0.81(x-y)^2 .
(x+y)^2-10(x+y)^2+25
6x^2(x-y)-10y(y-x)^2-2(y-x) 因式分解
