WebThe graphs of quadratic inequalities follow the same general relationship. Greater than inequalities are the region above the equation's graph and less than inequalities are made up by the region underneath the graph of the equation. What is the solution of a quadratic inequality? Below, you will learn a formula for solving quadratic inequalities. In solving quadratic equalities Sal was showing how to solve for f (x) = 0. Meaning the points at which the f (x) line crosses or intersects the x-axis (=0). In solving quadratic INequalities Sal shows how you can solve for f (x) > 0 or f (x) < 0. Meaning the x coordinates at which point the f (x) line is above (>) or below (<) the x-axis (0).
