TopicStandard Integrals and Reverse Chain Rule
DifficultyStandard +0.3 This requires expanding (2x^(3/2) - 1)^2 algebraically, then integrating term-by-term using standard power rule. It's slightly above average difficulty due to the fractional powers and need for careful algebraic manipulation, but remains a straightforward C2-level exercise with no conceptual challenges beyond basic technique.
