<h2>The answer is Option A!</h2>

$(x + 2 \sqrt{3} i)(x - 2 \sqrt{3}i )$

Let's see what complex numbers are!

$(x + 2 \sqrt{3 }i )(x - 2 \sqrt{3}i ) \\ = {x}^{2} - 2 \sqrt{3} x + 2 \sqrt{3} x - {(2 \sqrt{3} i)}^{2} \\ = {x}^{2} - {(2 \sqrt{3}i) }^{2}$

Now we know,

${i}^{2} = - 1$

So!

$= {x}^{2} - 12 \times( - 1)$

$= {x}^{2} + 12$

And thus we get the answer!

HELP. NEED HELP FAST

Zielflug [23.3K]

Answer:

C. 3

Step-by-step explanation:

8 / 1/3

When dividing fractions, do CCF (Copy, Change, Flip)

You keep the first number: 8

Change the division sign to multiplication: X

Flip the fraction to make it its reciprocal: 3/1

New expression:

8 X 3/1 or 8 X 3

What is the x intercept of the function

Svetllana [295]

Step-by-step explanation:

0 = sqrt(x - 4) + 3 Set equation equal to 0

-3 = sqrt(x - 4). Subtract 3 from both sides

the principle square root will only output positive values, since if it every outputted a negative value it would not be a function since a function cannot have 2 outputs for the same input.

no x-intercept
