Question

Find the discriminant of the quadratic equation 13root3xsquare + 10x + root3 = 0

Answer 1

13√3x² + 10x + √3 = 0

a = 13√3           b = 10                 c = √3

Discriminant = b² - 4ac
                       = 10² - 4 × 13√3 × √3
                      = 100 - 4 × 39
                      = 100 - 156
                      = -56
Discriminant = -56
