Question

How do you factor `8x^2+2xb`?

Answer 1

`=>2x(4x+b)`

Explanation:

You look for common values and variables.

Both terms have `2x` as a common factor. Lets see what this looks like:

`=>2x(4x+b)`

There are no more common factors. However, if you were pushed you could factor out the 4 but in doing so you would need to incorporate a correction in the form of `1/4`. Let me show you what I mean:

`=>2x xx4(x+b/4)` However, I can not see any benefit in doing this!
