What is the discriminant of the quadratic equation 0 = 2x2 3x - 5? - 37 - 31 43 49

The discriminant of a quadratic equation is useful in determining the nature of its roots. Further, it can be solved by the equation,

D = b² - 4ac

From the given equation, b = 3, a = 2, and c = - 5. Substituting the given to the equation,

D = 3² - (4) (2) (-5) = 49

Thus, the answer is the fourth choice, 49.
