The discriminant of a quadratic equation in the form ax^2 + bx + c = 0 is given by the formula B^2 - 4ac, where B represents the coefficient of x and a and c represent the coefficients of x^2 and the constant term respectively.
In this case, the coefficient of x^2 is -9, the coefficient of x is -3, and the constant term is -1.
Therefore, the discriminant is calculated as follows:
(-3)^2 - 4(-9)(-1) = 9 - 36 = -27
The discriminant of the given quadratic equation is -27.
