In this section, you'll learn how to find the sum and product of roots of quadratics. You'll also learn how to check solutions to quadratic equations in standard form using the sum and product of roots. The sum and product of the roots should be \(-b / a\) and \(c / a,\) respectively. We're going to practice checking solutions when solving quadratics in standard form by factoring. Thus, you should be able to solve quadratics by factoring before attempting this section.
