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
