Here's one exactly like yours. Use it as a guide. Factor 4a+24+ab+6b Factor the first two terms by factoring out 4 4(a+6)+ab+6b Factor the last two terms by factoring out b 4(a+6)+b(a+6) Now there is an (a+b) in each part: We factor out the (a+b) and have 4 and +b left (a+b)(4+b) Now do yours the exact same way.
