Hi,

my math lector gave me the following "homework"

calculate the definite integral:

I tried using substitution where U=√(x^2+2x) and dx=(3*du)/2*(x^2+x^3/3)^3/2 but I don't really know where to go with this problem

∫[0,2] √(x^2+2x)*(2x+2) dx

the intgegral is between 0 to 2..... ∫[0,2]

Thank you in advance.....
