Answer

Therefore, the value of the discriminant is $\boxed{-4}$.

Steps

Step 1 ：Given that a = -2, b = 2, and c = -1.

Step 2 ：The discriminant of a quadratic equation is given by the formula $D = b^2 - 4ac$.

Step 3 ：Substitute these values into the formula to find the value of the discriminant.

Step 4 ：So, $D = (2)^2 - 4*(-2)*(-1)$.

Step 5 ：Therefore, the value of the discriminant is $\boxed{-4}$.
