The quadratic equation which matches given solution is x² + 3x + 3 = 0. Then the correct option is C.
<h3>What is a quadratic equation?</h3>
It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
We know that the formula

The solutions are given below.

Then
1) 2x² + 6x + 9 = 0, the zeroes of the equation will be

2) x² + 3x + 12 = 0, the zeroes of the equation will be

3) x² + 3x + 3 = 0, the zeroes of the equation will be

4) 2x² + 6x + 3 = 0, the zeroes of the equation will be

Answer:
x≈ -4.71
Step-by-step explanation:
7(x+6)=9
Distribute the 7 into the parenthesis.
7x+ 7(6)= 9
Multiply the numbers.
7x+ 42= 9
Subtract from both sides.
7x+42= 9
-42 -42
Now, divide to both sides.
<u> 7x</u>= <u>-33</u>
7 7
x= -4.71428571429
x≈ -4.71
