Really really basic factorization

Hi all,

I feel pretty dumb posting this up, but here we go.

Factorise -


I don't know why, I just never seem to be able to find the right combination for these.

I know we're meant to type out a common factor, I can't spot it though :(

I.e. for ax + bx + ay + by = a (x + y) + b (x + y) -> (a + b)(x + y)

Anyone want to point out the obvious combination for me?

Erm , i think this will work .

Thanks mate, I knew I was missing something. Just wasn't in the form I was expecting. I really need to stop expecting certain answers out of math questions and look at them objectively :)

Appreciate it.
