Answer 1

Step-by-step explanation:

mark me as the BRAINLIEST

Answer 2

First Method

Using identity => a^2-b^2= (a+b)(a-b)

(2x+√3) (2x-√3)

$= ( {2x})^{2} - ( \sqrt{3} ) ^{2} \\ = 4x^{2} - 3$

Second Method

$(2x + \sqrt{3} )(2x - \sqrt{3} ) \\ = 2x(2x - \sqrt{3} ) + \sqrt{3} (2x - \sqrt{3} ) \\ = 4 {x}^{2} - 2x \sqrt{3} + 2x \sqrt{3} - 3 \\ = 4 {x}^{2} - 3$
