(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Differentiate.

f(x) = (x) (square root of (x^{2}+5))

2. Relevant equations

3. The attempt at a solution

f(x) = (x) (square root of (x^{2}+5))

=(x)(x^{2}+5)^{1/2}

f'(x)=(x)1/2(x^{2}+5)^{-1/2}(2x)+(1)(x^{2}+5)

=x^{3}/(x^{2}+5)^{1/2}+(x^{2}+5)^{1/2}

I'm having problems simplifying. The answer in the back of the book is 2x^2 + 5 / Square root of x^2+5..
