x=3

Steps

Step 1 :Given the quadratic equation: x2+6x+9=0

Step 2 :Use the quadratic formula: x=b±b24ac2a

Step 3 :Substitute the coefficients: a = 1, b = 6, and c = 9

Step 4 :Calculate the discriminant: Δ=b24ac=624(1)(9)=0

Step 5 :Since the discriminant is 0, there is only one solution for x.

Step 6 :Find the solution: x=6±02(1)=3

Step 7 :x=3
