To solve and graph systems of quadratic inequalities
Systems of Quadratic Inequalities
By drawing a second parabola in the Solve It, you created a quadratic system.
Essential Understanding You can solve systems involving quadratic equations using methods similar to the ones used to solve systems of linear equations.
The points where the graphs of the equations intersect represent the solutions of a system.
A system of one quadratic equation and one linear equation can have two solutions, one solution, or no solution.
Two solutions
One solution
No solution
