ABSTRACT
A quadratic equation that includes terms in both x and x2 cannot be rearranged to get a single term in x, so we cannot use the method used to solve linear equations.
There are three possible methods one might try to use to solve for the unknown in a quadratic equation:
(i) by plotting a graph (ii) by factorization
(iii) using the quadratic ‘formula’ In the next three sections we shall see how each can be used to tackle the following question.
