A critical number in a quadratic inequality is a number that makes the given polynomial equal to zero. It is used to help determine those values that make the inequality true. Finding the critical numbers on a number line for a quadratic inequality: 1. Set ax2 + bx + c = 0 and solve for x by factoring. 2.

Solving a Quadratic Inequality. Suppose we want to solve the quadratic inequality. This means we want to find what values of x make the function positive. So let’s sketch a graph of and see when it is positive. It is positive when the graph is above the x-axis. So what information do we need to have a “good enough” sketch to get this ...
