How to Solve Quadratic Inequalities. how to solve inequalities bbc bitesize tags : graph depicting the region x is equal to or less than 1, and y is , Notice that we change round the order of the first part, but it still , Solving inequalities (two step) MNM for Students , BBC KS3 Bitesize Maths Inequalities and Simultaneous Equations , Two graphs are given as y = 0.5x and y = 2x 6. Instead of using an equals sign, however, the inequality symbol is used throughout. Whatever form your quadratic equation is in, the first thing you need to do in solving it is to get a zero on one side of the brackets. The product of $$x + 1$$ and $$x - 5$$ is 0, so one or both brackets must also be equal to 0. Get Started Professional Solving Equations and Inequalities teaching resources.
