Factor m^2-k^2+6k-9

^2 means squared. I don't know any other way to type it. Thanks.

Seems to me you can only do this in 2 pieces...factor the first 2, then the last 2...

(m+k)(m-k) + 3(2k+3)

Whadya think?

hmmm...
I looked in the back of the book and it says...
(m-k+3)(m+k-3)
I don't know how to get to this though.
I probably should have told you the answer earlier, it might have helped.
Know how to get to that?

Sorry, I don't. Maybe someone else does! Perhaps you should post this question again so other responders will see it and won't think it's already answered. And I think it's a good idea to post the answer like you just did, so they'll know you're not just looking for the answer!
