First off, factoring would be useless for this question, because it is not asking for roots of any sorts, so we can drop the parenthesis and just combine like terms. First, a^2s 2a^2 + 4a^2 = 6a^2 So we can eliminate the top two options. Now the abs ab + (-3ab) = -2ab From this we can see the answer is the third option. 6a^2 -2ab + 2b + 9 I hope this Helps!
