Question

$(3 + \sqrt{3} ) (3 - \sqrt{3)}$
find it​

Answer 1

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

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

$9 - 3$

$= 6$

Hope it helps ✌️

Answer 2

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

By using ( a - b ) ( a + b ) = a^2 - b^2

$3^{2}- \sqrt{3}^{2}$

$9 - 3$

$6 \ ( Ans )$
