Factor

How do I factor these:
2x2 - 16x + 30
4x^2-9
x^2-5x
5x^2-26x+5
25x^2+4

Example:

2x^2 - 16x + 30 =

2 (x^2 - 8 x + 15)

2(x - 5)(x - 3)









The first, factor out a 2 first. Then factor .
The second...difference of two squares
Third factor out an x

I will be happy to critique your work. You need to do some trial and error.

    There are two solutions to | 16x - 5 | = 3. The greatest solution is ___. Since the expression, 16x - 5, can be either positive or negative, solve for both. 16x - 5 = 3 16x = 8 x = .5 -(16x - 5) = 3 -16x + 5 = 3 -16x = -2 x = 1/8
