engineering mathematics MCQ #3694

  1. Question 1

    Q1. The partial fraction decomposition of (x + 2) / (x² + 2x + 1) is

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

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

    Explanation: Decomposing (x + 2) / (x + 1)² into partial fractions, we get 1 / (x + 1) + 1 / (x + 1)².
