In Solving Quadratic Systems, you will learn how to deal with linear quadratic systems, quadratic quadratic systems, and systems of quadratic inequalities. Four video examples at the end make sure you have enough practice of the new concepts.
In a linear-quadratic system, use substitution to solve.
In a quadratic-quadratic system, use elimination to solve.
When graphing inequalities, remember the conventions about graphing boundaries using either solid or dotted lines.
If possible, check your solutions to systems of equations by graphing.
