16-8（x-y）+(x-y)^2化简
16-8（x-y）+(x-y)^2化简
16-8（x-y）+(x-y)^2化简
16-8（x-y）+(x-y)^2
=(4-x+y)^2
16-8（x-y）+(x-y)^2
=(x-y-4)²
你猜猜看！I don`t know
16-8（x-y）+(x-y)^2化简
化简y(x+y)+(x+y)(x-y)-x^2
16-8（x-y)+(x-y)2
若x-y=1 化简（x+y)(x^2+y^2)(x^4+y^4)(x^8+y^8)(x^16+y^16)
【2(x-y)(x-y)(x-y)-8(x-y)(x-y)(x+y)+6y(x-y)(x-y)]/2(x-y)(x-y)
化简 (x+2)平方-（x-y）(y-x)是(x+y)平方-（x-y）(y-x)
化简(2x/(x+y)-4x/(y-x))/8x(x^2-y^2)得
（x-2y）²+16y-8x+16
16-8（x-y）+（x-y）^2因式分解
16-8（x-y）+（x-y）^2
化简 x-y+（2y²）/（x+y）
化简:（x+y）+(2x+y/1*2)+(3x+y/2*3)+...+(9x+y/8*9)
-(x-y)^2-2(y-x)^2-5(x-y)^2+8(x-y)^2化简
(x+2y)(x-2y)(x^4-8x^2y^2+16y^4）如何解
化简x+y分之x²-y²-2X-y分之4x（x-y）+y²
2(x-y)+3（x+y）2-5(x-y)-8（x+y）2-（x-y）
化简(4x-2y)-[5x-(8y-2x-x-y)]+x
化简(4x-2y)-﹛5x-[8y-2x-(x+y)]-x﹜
