I need help with factoring trinomials completely. My teacher's example is:

Question

2x^2-12x+18
2(x^2-6x+9)
2(x-3)(x-3)

I need help with:
6x^2-26x-20

I just can't get this stuff so if you can please help me I'd greatly appreciate it.

Answer 1

6x^2-26x-20 =

2(3x^2 - 13 x - 10) =

2(3 x + 2)(x - 5)

Answer 2

Wow, thanks, now there is one more type I am stuck on and it is:
6y^2-24

Answer 3

6(y^2-4)
6(y-2)(y+2)...

Answer 4

Incredible. Thanks you two, you really helped me.
