This week in math we learned how to solve inequalities, specifically, quadratic inequalities. To solve for these inequalities we require the “zeros” of the quadratic, this means that we must factor the quadratic. With the “zeros” or roots we can use a simple visual tool to find the corresponding solutions, a number line. Inputting the roots on the number line allows us to visually see and test the numbers in-between, above, and below, the roots. This shows us where the solution makes sense in relation to the inequality. Here is an example.
