### Instruction: help me answer this question Find the discriminant of the quadratic equation -x^2 + x - 2 = 0., think step by step
### Assistant:  , The answer is The discriminant (D) of the quadratic equation ax^2 + bx + c = 0 is given by the formula D = b^2 - 4ac. For the given equation, a = -1, b = 1, and c = -2. Substituting these values into the formula, we get D = (1)^2 - 4*(-1)*(-2) = -7.
