Question

$( \sqrt{2}x + 3)( \sqrt{2}x - 3)$
plz give me ans with full solution

pls answer this peaceful​

Answer 1

Answer:

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

$\implies \: \: \left(\sqrt{2x}\right)^{2}-3^{2}$

$\implies \: \: 2x-9$

this is an answer for this question.

Answer 2

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

By using algebraic identity a²-b²=(a+b)(a-b), we have:-

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

$=> 2x^{2} -9$
