Question

here is a question for you guys
$(3 + \sqrt{3)} (3 - \sqrt{2)}$
pls do this to became a brain lest
​

Answer 1

Given,

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

In this question, we will apply an Identity of Chapter Polynomial i.e.

=> (x+a)(x+b) = x^2 + (a+b)x+ ab

Expn:-

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

$\implies 9 + 3\sqrt{3} - 3\sqrt{2} + \sqrt{6}$
