This one is similar to the one I explained the other day, except that the denominator power is not 1 (ie the overall function power is not -1).

2t is the derivative of t^2, so this function follows the formula f’(x) [f(x)]^n which integrates to becomes [f(x)]^(n + 1) divided by (n + 1).

It’s basically akin to integrating x^n, except that this time it’s f(x) instead of x (so we need the “accompanying” f’(x)).
