A quadratic equation is an equation whose highest power on its variable(s) is 2. The quadratic formula is a formula which can be used to find the roots of (solve) a quadratic equation. The quadratic formula is given by x = (-b +/- sqrt(b^2 - 4ac)) / 2a, where a is the coefficient of the quadratic term (x^2), b is the coefficient of the linear term (x) and c is the constant term. Thus, to solve a quadratic equation using the quadratic formula, first identify the 'a', 'b' and the 'c' of the quadratic equation and plug them into the quadratic formula and evaluate accordingly. Note that if the 'a', 'b', or/and the 'c' of the quadratic equation is/are fraction(s), then it can be simpler to evaluate the quadratic equation by first getting rid of the fraction(s) by first multiplying through by the LCM of the denominator(s) of the fraction(s) before extracting a, b and c.\n
