1、(a-b)(x-y)-(b-a)(x+y)
2、(2a+b)^2 +8ab
3、16x^4-1
4、x^2-5x+36
5、x^2-16x+36

1：
=（a-b)(x-y-x-y)
=(a-b)(-2y)
2:
=4a^2+4ab+b^2+8ab
=4a^2+12ab+b^2
3:
=[(4x)^4+1][(2x)^2+1]][(2x)^2-1]
4:
=(x-9)(x+4)
5:
=(x-12)(x-3)
没法写过程,
到底是不是分解因式

1、(a-b)(x-y)-(b-a)(x+y) (a+b)(x+y)-(a+b)(x-y)分解因式因式分解,（a-b)(x-y)-(b-a)(x-y) (a-b)(x-y)+(b-a)(y-x) (5)a(x+y)-b(x+y)-x-y (x+y)(a-2b) 因式分解 (1)6(x-y)^3-3y(y-x)^2 (2)x(x-y)(a-b)-y(y-x)( (1).(x+y)(a+2b) a/b = 1-x/y 求b/a 应是分解a^2(a-b)+(b-a)(x-y)^2-2(y-x)+1 (1) (a+2b/a-b)+(b/b-a)-(2a/a-b); (2) (y/x-y+z)+(2x+z/y-x-z)- (3x-y)(3x+y)+y(x+y);(a+1/2b)(a-1/2b)-(3a-2b)(3a+2b)快点,
