engineering mathematics MCQ #3682

  1. Question 1

    Q1. The partial fraction decomposition of (x + 3) / (x² + 2x + 1) is

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

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

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