How do you do some of these type of problems? It's my homework and I didn't really understand in class.
a^3-4a^2-a+4 or cx+cy+bx+by it's algebra 1 or algebra 2, btw. |

^ (a^2 - 1), I forgot what that's called but it's just a quadratic. The "a" is gone because they've canceled each other out, so basically you're looking for two numbers that multiply to -1 and add to 0. And that's easy, because that's just 1 and -1. So you'll get (a - 1)(a + 1)
