### Instruction: help me answer this question Solve the quadratic equation x2 + 3x + 9 = 0, think step by step
### Assistant: Comparing the given equation with ax2 + bx + c = 0, we have a = 1, b = 3, and c = 9. The discriminant (D) is calculated as D = b2 - 4ac = 32 - 4 × 1 × 9 = -27. Since D < 0, the roots of the equation are given by x = [-b ± √(b2 - 4ac)]/2a = [-3 ± √(-27)]/2 = -1.5 ± 1.5√3. , The answer is x = -1.5 ± 1.5√3
