  1. Question 1

    Q1. The partial fraction decomposition of 1 / (x² + 5x + 6) is

    • A) 1 / (x + 2) + 1 / (x + 3)
    • B) -1 / (x + 2) + 1 / (x + 3)
    • C) 1 / (x + 3) - 1 / (x + 2)
    • D) -1 / (x + 3) + 1 / (x + 2)

    Answer: -1 / (x + 2) + 1 / (x + 3)

    Explanation: Factor denominator, then decompose 1 / (x + 2)(x + 3) into A / (x + 2) + B / (x + 3).
