Math Tutoring on Solving Quadratic Inequalities
A second-degree polynomial function is known as Quadratic function. When these types of functions use inequality symbols which include the symbols known as less than <, greater than ˃, less than or equal to ≤, and greater than or equal to ≥, the expression is called Quadratic Inequality.
Guidelines for solving polynomial inequalities:
Step 1: Find all of the 0s of the polynomial or in this case the quadratics and then arrange the 0s in increasing order. The zeros are called its critical number.
Step 2: Plot the numbers on the number line as open or closed points based upon the original inequality symbol.
Step 3: Choose a test value in each interval to see if it satisfies inequality or not. If the test value produces a true statement, the entire interval is true and if the test value produces a false statement, the entire interval is false.
