WebHow do I solve quadratic inequalities? STEP 1: Rearrange the inequality into quadratic form with a positive squared term. ax 2 + bx + c > 0 (>, <, ≤ or ≥); STEP 2: Find the roots of the quadratic equation . Solve ax 2 + bx + c = 0 to get x 1 and x 2 where x 1 < x 2; STEP 3: Sketch a graph of the quadratic and label the roots. As the squared term is positive it will be "U" … WebExample 4: Solving a Quadratic Inequality Using a Graph. Solve the inequality 2 𝑥 ≤ 1 5 𝑥 − 2 7 . Answer . We begin by simplifying the given inequality to the point where one side of it is zero. We can subtract 1 5 𝑥 from both sides, which gives us 2 𝑥 ≤ 1 5 𝑥 − 2 7 2 𝑥 − 1 5 𝑥 ≤ − 2 7. darty office https://jezroc.com
