There is no one solution method to solve all integration problems. (Solving them is an ongoing topic of mathematical research. The field is called "differential equations").

Things to try: break up addition and subtraction and factor constants out of the integral
Substitution (often called u-substitution).
Integration by parts. Trig substitution. Partial fractions. Miscellaneous substitutions. Geometric arguments (integral as area) .
That's about it for elementary methods.
