16-8（x-y)+(x-y)216-8（x-y)+(x-y)216-8（x-y)+(x-y)2解16-8（x-y)+(x-y)2=(x-y)2-8（x-y)+16=(x-y)2-8（x-y)+4^2
16-8（x-y)+(x-y)2
16-8（x-y)+(x-y)2
16-8（x-y)+(x-y)2
解16-8（x-y)+(x-y)2
=(x-y)2-8（x-y)+16
=(x-y)2-8（x-y)+4^2
=[(x-y)-4]^2
=(x-y-4)^2
16-8（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)
若x-y=1 化简（x+y)(x^2+y^2)(x^4+y^4)(x^8+y^8)(x^16+y^16)
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
16-8(x-y)+(x-y)平方
(x+y)^2-16(x-y)^2
(x+y)^2-16(x-y)^2
(x-y)²-8(x-y-2)
-8(y-x)^2×(x-y)
(2x+y)²+(x+3y)(x-3y)-x(5x+8y)因式分解
[2(x-y)^5-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2[2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2
化简y(x+y)+(x+y)(x-y)-x^2
(x-2y)^2+16y-8x+16因式分解
（x-2y）²+16y-8x+16
(x-2y)的平方+16y-8x+16
x^4+16y^4+8x^2y^2
x^4-8x^2y^2+16y^4
8x^2y^2-x^4-16y^4
