Rewrite in terms of u: Rewrite the integral in terms of u.∫x2(6−x3)5dx=∫(6−u)5⋅(−31)du
Integrate with respect to u: Now, integrate (6−u)5∗(−31) with respect to u.∫(6−u)5∗(−31)du=(−31)∗∫(6−u)5du
Expand and integrate term by term: Expand (6−u)5 and integrate term by term.(−31)×∫(6−u)5du=(−31)×[665×u−75×64×u2+810×63×u3−910×62×u4+105×6×u5−6u6]+C
