The discriminant is -32.
The discriminant is 9.
Discriminant = b2-4ac = (-2)2-(4*4*4) = -60
If you mean b^2 -4ac then it is the discriminant of a quadratic equation. If the discriminant equals 0 then the equation has 2 equal roots. If the discriminant is greater than 0 then the equation has 2 different roots. If the discriminant is less than 0 then it has no real roots.
