Question

EVALUATE
$(\sqrt{3 } + 2)( \sqrt{3} - 2)$
​

Answer 1

Given to evaluate:-

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

Solution:-

First of all, we have to know the identity used to solve the question.

$1. \: \: (x + y)(x - y) = {x}^{2} - {y}^{2}$

Calculation:-

From identity, we can say that,

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

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

$= 3 - 4$

$= - 1$

Answer:-

$Answer \: = -1$
