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

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

More about the quadratic equation link is given below.

Answer:

d. static

Step-by-step explanation:

This is a question about Java programming.

A class contains information about it's members(objects). Private, public or inline variables must be related to an object, that is, an object has to be created before the variable is acessed.

Static variables, otherwise, may pertain to the class, and not to the object, that is, and thus, the correct answer is given by option d.
