1) [tex]f(x)=\frac { { x }^{ 2 } }{ \sqrt { x+1 } } \\ f'(x)=\frac { 2x\sqrt { x+1 } -\frac { \sqrt { x+1 } }{ 2 } }{ x+1 } \\ f'(x)=\frac { x(3x+4) }{ 2{ (x+1) }^{ \frac { 3 }{ 2 } } } [/tex]
Can somebody show how you can get from the second step to the third step? I tried factoring x+1 from the numerator but it just made it even messier.
2)
Can somebody tell me what method/technique or what theorem I need to use in order to do this question?
