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: The answer is (B). paragraph.
Step-by-step explanation: We are asked the form which a flowchart proof uses to present a logical argument.
A flow chart proof is a map which shows the statements and reasons needed for a proof in a structure that helps to indicate the logical order. The reasons and conclusions are written in the form of paragraphs in the proof.
Therefore, the complete statement is
"A flowchart proof uses a <u>paragraph</u> form to present a logical argument.
Thus, (B) is the correct option.
