WebMay 13, 2024 · Explanation: To start with, we can rearrange the enumerator as follows: ∫ x − 1 (x + 1)2 dx = = ∫ (x +1) −2 (x +1)2 dx. Now, we may interpret x + 1 as an inner function, and thus this is the same as [∫ t −2 t2 dt]t=x+1 = = [∫ 1 t dt − 2∫ 1 t2 dt]t=x+1 = = [ln t + 2 t +C]t=x+1 = = ln x +1 + 2 x + 1 +C.
