Question

I need help simplifying this ALG. 2 problem.

Answer 1

well the denominator is the difference of 2 squares

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

so your denominator is

\[(\sqrt{5})^2 - (\sqrt{2})^2\]

so the denominator is 3

so you now have

\[\frac{6(\sqrt{5} + \sqrt{2})}{3}\]

cancel the common factor of 3 to get your answer

Answer 2

GOD BLESS YOU! @campbell_st
