Previously, you have learnt how to solve quadratic inequalities where the portion of the curve is below the x-axis. In this post, you will be learning how to solve quadratic inequalities where the portion of the curve is above the x-axis. Not to worry, the solving style is the same, so there is not much new things to learn here.
Now that you have learnt how to solve quadratic inequalities, let’s move on to discriminant, which is a new concept in Secondary 3 Additional Mathematics.
