WebExample. Our goal is to find the number of solutions to this quadratic equation: 9 x 2 + 42 x + 49 = 0. Our first order of business is to identify the coefficients a, b, and c (this helps us calculate the discriminant): a = 9, b = 42, c = 49. We’ve identified the coefficients, so we can evaluate the discriminant by substituting these ... WebThere can be more than one solution. Example: (x−3) (x−2) = 0 When x is 3 we get: (3−3) (3−2) = 0 × 1 = 0 which is true And when x is 2 we get: (2−3) (2−2) = (−1) × 0 = 0 which is …
