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 89. Therefore, the correct answer is D.89.
