  1. Question 1

    Q1. The partial fraction decomposition of (x² + 1) / (x + 1)(x - 1) is

    • A) 1 + 1 / (x + 1) + 1 / (x - 1)
    • B) 1 + 1 / (x - 1) - 1 / (x + 1)
    • C) 1 - 1 / (x + 1) + 1 / (x - 1)
    • D) 1 - 1 / (x - 1) + 1 / (x + 1)

    Answer: 1 + 1 / (x - 1) - 1 / (x + 1)

    Explanation: Divide numerator by denominator to simplify, then apply partial fractions.
