PDF Quadratic Equations – The general form of a quadratic equation is ax2 + bx + c = 0 where a, b, c are real numbers and a 0. There will be two roots for a quadratic equation and can be found by solving the equation ax2 + bx + c = 0. Roots are also called solutions of ax2 + bx + c = 0. Exercise 1: (i) Check whether the following equations are quadratic or not: (a) 4x2Q.

In the definition above, notice that if \(a\) is zero, there is no \(x\)-squared term, so the function is not quadratic (it would then be linear).
