A student was given the following poblem:

4x^2 - 9

___________ * 6x - 9

4x^ + 12 +9

He states his answer to the problem as 3(2x - 3). Is the answer correct? If not, explain why. What would you suggest he do to solve the problem.

The above is the problem as presented to me. I do not have a clue as to how to answer it! Thanks
