Answer:

x=9

Step-by-step explanation:

Divide both sides by 12. The 12 on the left side cancels out. You are left with x=(108/12) which is the same as x=9.

Which equation has the solutions x = startfraction negative 3 plus-or-minus startroot 3 endroot i over 2 endfraction? 2x2 6x 9 =
Gennadij [26K]

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

\rm x = \dfrac{-b\pm \sqrt{b^2-4ac}}{2a}

The solutions are given below.

\rm x = \dfrac{-3 \pm \sqrt3 \iota }{2}

Then

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

\rm x = \dfrac{-6\pm 6\iota}{4}\\\\x = \dfrac{-3\pm 3 \iota}{2}

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

\rm x = \dfrac{-3\pm \sqrt{39}\iota}{2}

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

\rm x = \dfrac{-3\pm \sqrt3\iota}{2}

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

\rm x = \dfrac{-6\pm 2\sqrt{3}}{4}\\\\x = \dfrac{-3\pm \sqrt3 }{2}
