This week in pre-calculus 11 we learned about how to solve quadratic systems.

Most questions were based on two lines either quadratic-quadratic or linear-quadratic. There are multiple ways of find the solution for where both lines cross, like graphing or elimination. However, in class we learned about the process of substitution. This is the process of removing one variable from the equation, then solving for the remaining unknown variable then using that answer to find the first unknown variable.

It will look like this:
