	Algebra I: Solving with the quadratic formula

In this section, you'll learn another approach to using the quadratic formula. If the left hand side of a given equation ax² + bx + c = 0 cannot be factorized easily into the product of a pair of binomials, then it can be solved by using the quadratic formula x = {-b

(b² - 4ac)}/2a and it'll have two roots. For example, if you use the quadratic formula to solve equation x² + 2x + 7, you get two roots x = -1
