Anyone know of any resources that can help me with these types of questions? I seem to be falling a step short in factoring the quadratic.

You might consider looking at Magoosh test prep (https://gmat.magoosh.com/) --- we have a couple hundred lesson videos, including a series of videos explaining everything you need to know about quadratics. We also have 800+ practice questions, each with a video explanation, so you can get immediate feedback right after doing each question.

You can read our testimonials and score guarantee at the link above.

Here's a sample lesson, on the FOIL method . . .

Here's a sample question about a quadratic:
https://gmat.magoosh.com/questions/117

When you submit your answer to that sample question, the next page will have the video explanation.

If you have any questions on this, please let me know.
