Well, if each factor had a 5x and each factor had a -4, that would take care of the and constant terms, so let's see what happens to the middle term:

. Yep, that does it.

. This one has at least one x in every term, so you can start by factoring out an x.

.

Now, and , so the rest of this thing should factor to:

Check by multiplying it out: . Yep, that works.
