Answer 2

ANSWER

A.
$- 9$

EXPLANATION

The given expression is

$3( \frac{14}{ {4}^{2} - {3}^{2} } - 5)$

Recall that,

${a}^{2} - {b}^{2} = (a - b)(a + b)$

We apply the difference of two squares formula to factor the numerator to obtain,



$= 3( \frac{14}{ (4 - 3)(4 + 3) } - 5)$
We simplify the factors in the denominator to get,

$= 3( \frac{14}{ (1)(7) } - 5)$
Let us cancel out the common factors now to get,

$= 3( 2 - 5)$


This will give us,

$= 3( - 3) = - 9$


The correct answer is A.
