1 x^{2}+6 x+9=0

Question

1 x^{2}+6 x+9=0

Accepted Answer

Step:1 ：Given the quadratic equation: (x^2 + 6x + 9 = 0)Step:2 ：Use the quadratic formula: (x = frac{-b pm sqrt{b^2 - 4ac}}{2a})Step:3 ：Substitute the coefficients: a = 1, b = 6, and c = 9Step:4 ：Calculate the discriminant: (Delta = b^2 - 4ac = 6^2 - 4(1)(9) = 0)Step:5 ：Since the discriminant is 0, there is only one solution for x.Step:6 ：Find the solution: (x = frac{-6 pm sqrt{0}}{2(1)} = -3)Step:7 ：(boxed{x = -3})
