Best ResponseYou've already chosen the best response.0This is how I'm reading the integral given, the integral of {(x^2)/[(x1)(x1)(x+3)]} dx from 2 to a as a grows unbounded (or approaches infinity as many like to say). When x=2, (x^2)/[(x1)(x1)(x+3)] is 4/5, and this value is the initial point of the integral. This means this 4/5 is less than or equal to the integral over our given bounds (2+) since the derivative of the polynomial is positive over the same bounds of integration so the integral is constantly getting a little positive addition to it. The integral of 4/5 over the same bound clearly grows unbounded or diverges, and since the integral of 4/5 is smaller at every point within the bounds of integration than the given integral, then the given integral must diverge too.
