(a+b)(a-4c)
Just a quadratic. It is the lack of numbers which makes it daunting. Just think about it, group like terms and expand to check

You should really learn more about math before trying to post help in this, or any other, section/place/forum. A quadratic equation is an equation in which the highest quantity is a square. Therefore, factoring them, as Assassin said, is very simple and straight forward.

I'm currently in Calculus, and I beg to differ.
A quadratic is just an equation. Equations aren't part of Algebra 1? lol? |
