TopicStandard Integrals and Reverse Chain Rule
TypeFind indefinite integral of polynomial/power
DifficultyEasy -1.2 This is a straightforward application of the power rule for integration to two simple terms. It requires only direct recall of standard integral formulas with no problem-solving, making it easier than average but not trivial since it includes a negative power term that students must handle correctly.
