Answer

Therefore, the value of the discriminant is 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=b24ac.

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

Step 4 :So, D=(2)24(2)(1).

Step 5 :Therefore, the value of the discriminant is 4.
