  1. Question 1

    Q1. Resolve (2x + 1) / (x - 1)(x + 2) into partial fractions.

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

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

    Explanation: Let (2x+1)/((x-1)(x+2)) = A/(x-1)+B/(x+2). Solving gives A=1 and B=1.
