Part A, factor by grouping.

mathmale · Answer

Hint:  (x+3) is one factor that will result to your factoring by grouping.

anonymous · Answer

what is part B

isaiah.feynman · Answer

If x+3=0, what x?? That's part B.

mathmale · Answer

Solving Part b requires that we solve Part a first. 

Please try factoring f(x) = 0.  

Hint:  (x+3) is one of the factors.  What are the other two factors?

anonymous · Answer

ok and what about part C

mathmale · Answer

Sorry, but we haven't finished parts a or b yet.  If you need help finishing part a, please say so and try to ask questions whose answers may lead to your finishing part a.
