In a previous post we looked at root-finding methods for single variable equations. In this post we’ll look at the expansion of Quasi-Newton methods to the multivariable case and look at one of the more widely-used algorithms today: Broyden’s Method.

**Motivation**

How do you find the roots of a continuous polynomial function? Well, if we want to find the roots of something like:
