Part I Solving a Quadratic Equation (2spoints A quadratic equation, also known as a second-degree polynomial eepsatim. s defined by where z represents the unknown and a, b, e are assumed to be real in this documnst, and a 0. This equation admits two solutions also called roots. The roots are 2a A-- 4oc denote the discriminant. We can distinguish three cases * -0. The quadratic equation has a double root and (2) simplifies tor-- Let A>0. The quadratic equation has two real roots given by (2) A
