I tired my best on this one...

4.(6y^2+4y-3)+ (3y^2+2)=

My WOrk=18y^4+12y-6

Unfortunately, your work is incorrect. Based on the original problem, it looks like you multiplied things together. The parentheses don't matter in this problem. Simply combine 6y^2 and 3y^2 to make 9y^2. Because there is only one monomial with just one y, you leave +4y alone. You then combine -3 and +2 to make -1. The answer is 9y^2+4y-1.
