engineering mathematics MCQ #3679

  1. Question 1

    Q1. Resolve (x² + 3x + 2) / (x + 1)(x + 2)² into partial fractions.

    • A) 1 / (x + 1) + 0 / (x + 2) + 0 / (x + 2)²
    • B) 1 / (x + 2) + 1 / (x + 2)²
    • C) 1 / (x + 1) + 1 / (x + 2)
    • D) 1 / (x + 1) + 0 / (x + 2) + 1 / (x + 2)²

    Answer: 1 / (x + 1) + 0 / (x + 2) + 0 / (x + 2)²

    Explanation: Simplify the expression before decomposing into partial fractions, (x + 1)(x + 2) / (x + 1)(x + 2)² = 1 / (x + 2).
