Without using a calculator, use the discriminant, b2 2 4ac, to determineSince 7 is not a perfect square, we cannot solve the equation by factoring. Previously we learned that since 169 is the square of 13, we can also say that 13 is a square root of 169. Also, (−13) 2 = 169, so −13 is also a square root of 169. Therefore, both 13 and −13 are square roots of 169.
