Question

Find The Sum And Express It In Simplest Form.
(ab+4a-6) + (ab+6)

Answer 1

All we have do is add "like" terms together. So any terms with both a and b we add, same with terms with just a or b and also terms without a or b.

So we have ab+ab +4a +6-6 which equals 2ab+4a (as the 6's cancel)
