Please help!! I keep solving this problem but I keep getting the wrong answer.
Find the derivative of the function:
f(x)= xsqrt(x1)/(x+2)

f = x√t(x1)/(x+2)
f' = [(x√(x1))'(x+2)  x√(x1)(1)]/(x+2)^2
= [{√(x1) + x/2√(x1)}(x+2)  x√(x1)]/(x+2)^2
= (x^2+6x4)/(2√(x1)(x+2)^2)
wolframalpha . com will show you the steps for almost any derivative you can throw at it.
