Given the function ????(????) = ????????^{2} + ???????? + ???? or ???? = ????????^{2} + ???????? + ????, where ????, ????, ???? are real numbers and ???? ≠ 0,if we set this function to be equal to zero we have ????????^{2} + ???????? + ???? =0. If you still remember, this resulted into quadratic equation form.

Therefore, in this module, you will learn to represent quadratic function using equation.
