1. Change the quadratic inequality to quadratic equation in standard form. Steps to follow in solving quadratic inequalities in one variable. 2. Find the roots of the corresponding equality by using any of the following methods: extracting the square roots, factoring, completing the square, or using quadratic formula. 3. Create intervals using the roots as critical x-values in dividing the number line into parts. 4. Test a number from each interval against the inequality. 5. Test the roots against the inequality. 6. Plot the roots on the number line. Solid circles are used in the graph if they are part of the solution set and open circles if not a solution. Darken the parts of the number line that represents the solution set. 7. Write the solution set of the inequality. Directions: Find the solution set of the following quadratic inequalities then graph. 1. x² - 6x + 5>0 2. 2x² ≥ 98 3. x² + 6x ≤ -8 4. 2x²-7x+ 3
