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

In the given equation -x² + 4x + 7 = 0, the coefficients are:
a = -1 (the coefficient of x²)
b = 4 (the coefficient of x)
c = 7 (the constant term)

Substituting these values into the discriminant formula gives:

D = b² - 4ac
D = (4)² - 4*(-1)*7
D = 16 + 28
D = 44

So, the discriminant of the equation -x² + 4x + 7 = 0 is 44.
