### Instruction: help me answer this question Solve the quadratic equation -x2 + x - 2 = 0, think step by step
### Assistant: Comparing the given equation with ax2 + bx + c = 0, we have a = -1, b = 1, and c = -2. The discriminant (D) is calculated as D = b2 - 4ac = 12 - 4 × (-1) × (-2) = 1 - 8 = -7. Since D < 0, there is no real solution for this equation. , The answer is There is no real solution for this equation
