To solve quadratic systems of equations, we are going to use similar methods that we used for solving linear systems, however, these systems are more complex. There are two types of quadratic functions that we are going to work with. The first one is the linear quadratic system. This system can be solved algebraically by isolating one of the variables in the linear equation and then substituting into the quadratic equation. In a quadratic - quadratic system, use elimination to solve. A quadratic system can have up to 4 solutions. This lecture also covers systems of quadratic inequalities. When graphing inequalities, remember the conventions about graphing boundaries using either solid or dotted lines.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
