Question

Solve

Answer 1

\[\sqrt{11}/2-\sqrt{5}\]

Answer 2

and by solve i mean rationalize the denominator.

Answer 3

use the fact that:\[a^2-b^2=(a+b)(a-b)\]to eliminate the radical in the denominator.

Answer 4

the denominator contains: \(2-\sqrt{5}\)

so if you multiply both the numerator and denominator by: \(2+\sqrt{5}\)
then the radical should disappear from the denominator

Answer 5

awesome, thanks for the help!
