Ex 7.4, 24 𝑑𝑥 𝑥2 + 2𝑥 + 2 equals A. x tan−1 (x + 1) + C B. tan− 1 (x + 1) + C C. (x + 1) tan−1 x + C D. tan−1 x + C 𝑑𝑥 𝑥2 + 2𝑥 + 2 = 𝑑𝑥 𝑥2 + 2 𝑥 1 + 2 = 𝑑𝑥 𝑥2 + 2 𝑥 1 + 12 − 12 + 2 = 𝑑𝑥 𝑥 + 12 − 12 + 2 = 𝑑𝑥 𝑥 + 12 − 1 + 2 = 𝑑𝑥 𝑥 + 12 + 12 = 11 𝑡𝑎𝑛−1 𝑥 + 11 +𝐶 = 𝑡𝑎𝑛−1 𝑥+1 +𝐶 ∴ Option B is correct answer .
