Finding values of a for convergent integral from 1 to infinity

[erogol]

$$\int (((ax^2)/(x^3)+5) + 2 / x^3) dx$$ (one to infinite integral) find the all possible values of a?

I can't imagine your parentheses are correct...

Is this supposed to be:


$$\int_{1}^{\infty}\left({\frac{ax^2}{x^3+5}+\frac{2}{x^3}\right)dx$$
