for (i), both portions are algebraic.
when the 2 portions are different type, follow LiATE.
when the 2 portions are same type, differentiate the portion that is easier to differentiate & integrate the other portion.
for (ii), dx/du = -2u,
so substitute dx with (-2u)du

sorry, small typo error,
for part (ii), 3rd line, should be du, not dx.
