A system of equations refers to any problem that has more than one function rule, or equation where the variables represent the same unknown values. The solution is the point or points the two equations have in common. Previously you have solved systems of linear equations. In this section you will solve systems dealing with quadratic equations. There are 3 possibilities for solutions, see the diagrams below.
Watch the video examples below and take notes. Then complete the practice problems.
You can use your graphing calculator to find the solutions as well. Below are the steps when using a TI-84 calculator.
