"WebThe roots of the quadratic is given by x = {- b ± √ (b²-4ac)}/2a So if the discriminant b² - 4ac = 0, then the roots will be x = (- b ± 0)/2a i. e., - b/2 a, - b/2a. Hence the quadratic equation will have two roots which are equal and rational if the discriminant b² - 4ac = 0. " - If the discriminant is 0 how many roots
