Factoring is tricky but don't let it intimidate you. Just do this:

Now can you see that these highlighted terms cancel each other?

BUT when I say: "cancel" I'm not meaning that you can just just wipe out the (x + 4) in the numerator. Why? Well, when we "cancel" terms, we aren't just DELETING them! Think of this: = 1, right? Similarly, = 1, right?

SO when we cancel out the (x + 4) above, we are really saying that equals 1.

Therefore, this:

is really:

Does that make sense? I hope so. If you need more help with canceling and factoring, check out my YouTube videos. Just do a search on YouTube for PRMathChicago and when you find my name, you'll see some vids that my help you because they explain this in more detail.

Good luck. :-)
