  1. Question 1

    Q1. The partial fraction decomposition of (x + 2) / (x² - x - 6) is

    • A) 1 / (x - 3) + 0 / (x + 2)
    • B) 4 / 5(x - 3) + 1 / 5(x + 2)
    • C) -1 / 5(x + 2) + 4 / 5(x - 3)
    • D) 1 / (x + 2) + 1 / (x - 3)

    Answer: 4 / 5(x - 3) + 1 / 5(x + 2)

    Explanation: Factor denominator, then apply cover-up method to get A = 4/5 and B = 1/5.
