<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!

How many different four-letter arrangements can be formed using the six letters A, B, C, D, E and F, if the first letter must be

Ainat [17]

Answer with Step-by-step explanation:

We are given that A,B,C,D,E and F.

We have to find the number of different four -letter arrangements can be formed using given six letters a,if the first letter must be C and one of the other letters must be B and no letter can be used more than once in the arrangement.

Number of letters=6

We have to arrange four letter out of six

After fixing C and B then we choose only two letters out of remaining four letters and repetition is not allowed.

Permutation formula : $nP_r=\frac{n!}{(n-r)!}$

We have n=4 an r=2

Using this formula and substitute the values

Then, we get $4P_2=\frac{4!}{(4-2)!}=\frac{4\times 3\times 2!}{2!}$

$4P_2=4\times 3=12$

Hence, number of different four -letter arrangements can be formed using six letters when repetition is not allowed=12
