What is a Quadratic Equaion?
A quadratic equation is one where the highest degree of an equation is 2 (example $x^2 = 25$ is a quadratic because of the $2$ on the $x$.)
The prefix “quad” means square, so quadratic equations are ones where the variable gets squared (example $n^2 + 3 = 39$.)
In this video we look at how to factor a trinomial quadratic expression. The method works well when the coefficient in front of x squared is one.
