4x^2-37x+9因式分解

还有这些6x^2+13x-15 5x^2-2x-3 52xy-8ay+39bx-6ab
x^2-16y^2-8y-1 xy+1-x-y ab(a-b)+bc(b-c)+ca(c-a)
x^4-3x^2+1
解一下这个(x-y)^(2m)-(x-y)^(2m-2),都些出步骤，谢！

Answer 1

4x^2-37x+9=(4X-1)(X-9)
6x^2+13x-15=（6X-5)（X+3）
5x^2-2x-3=(5X+3)(X-1)
52xy-8ay+39bx-6ab=（4Y+3b）(13X-2a）
x^2-16y^2-8y-1=(X+4Y-1)(X-4Y+1)
xy+1-x-y=(Y-1)(X-1)
ab(a-b)+bc(b-c)+ca(c-a)=（a-c)(a-b)(b-c)
x^4-3x^2+1 =(X^2+X-1)(X^2-X-1)
记得给分哦

Answer 2

(4X-1)(X-9)
(6X-5)(X+3)
(5X+3)(X-1)
(13X-2a)(4y+3b)
(x+4y-1)(x-4y+1)
(x-1)(y-1)
(a-b)(b-c)(a-c)
(x-（根号下5+1）/2)（x-（根号下5-1）/2）（x+（根号下5+1）/2）（x+（根号下5—1）/2）
(x-y)^(2m-2)(x-y-1)(x-y+1)

Answer 3

(4X-1)(X-9)
(6X-5)(X+3)
(5X+3)(X-1)

Answer 4

（X-9)(4x-1)
