Question

simplify : (√3+2) (√3-2)​

Answer 1

Answer:

(a+b)(a-b) = a²-b²

√3²-2²=3-4=-1

Answer 2

Answer:

-1

Step-by-step explanation:

$= > ( \sqrt{3} + 2)( \sqrt{3} - 2) \\ by \: applying \: the \: idenity \: (a + b)(a - b) \\ = {a}^{2} - {b}^{2} \\ = > ({ \sqrt{3} })^{2} - ( {2})^{2} \\ = > 3 - 4 \\ = > - 1$
