= \int x^{15} + 30 x^{14} + 420 x^{13} + 3640 x^{12} + 21840 x^{11} + 96096 x^{10} + 320320 x^{9} + 823680 x^{8} + 1647360 x^{7} + 2562560 x^{6} + 3075072 x^{5} + 2795520 x^{4} + 1863680 x^{3} + 860160 x^{2} + 245760 x + 32768 d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int x^{15} d x + \int 30 x^{14} d x + \int 420 x^{13} d x + \int 3640 x^{12} d x + \int 21840 x^{11} d x + \int 96096 x^{10} d x + \int 320320 x^{9} d x + \int 823680 x^{8} d x + \int 1647360 x^{7} d x + \int 2562560 x^{6} d x + \int 3075072 x^{5} d x + \int 2795520 x^{4} d x + \int 1863680 x^{3} d x + \int 860160 x^{2} d x + \int 245760 x d x + \int 32768 d x
