The discriminant of a quadratic equation is given by the formula `b² - 4ac`, where a, b, and c are the coefficients of the quadratic equation `ax² + bx + c = 0`.

In the given equation `-x² - 3x - 5 = 0`, the coefficients are:
a = -1 (the coefficient of x²)
b = -3 (the coefficient of x)
c = -5 (the constant term)

Substituting these values into the formula for the discriminant gives:

Discriminant = (-3)² - 4*(-1)*(-5)
= 9 - 20
= -11

So, the discriminant of the equation `-x² - 3x - 5 = 0` is -11.
