1. If R(x) = (ax + b)/(Ax^2 + Bx + C) and (Ax^2 + Bx + C)’ = ax + b, use u-sub and the natural logarithm, regardless of whether (Ax^2 + Bx + C) is irreducible!
   1. Likewise check to see if small changes in constants, like factoring out a constant from numerator or denominator, will yield this case…
   2. or adding and subtracting in a term d/(Ax^2 + Bx + C) so that b + d = B and this method can be applied, while the new term –d/(Ax^2 + Bx + C) can be handled by (c) – (f).

A worked examples of at least one case of the sort in (g) is:
