Question
Solution 1
The discriminant of a quadratic equation ax² + bx + c is given by the formula D = b² - 4ac.
In this case, a = 2, b = 5, and c = -8.
Substituting these values into the formula, we get:
D = (5)² - 4*(2)*(-8) D = 25 - (-64) D = 25 + 64 D = 89
So, the discriminant of the polynomial 2x² + 5x - 8 is 8 Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
