NUST NET Mathematics — Partial Fractions
Partial Fractions is part of the FSc Mathematics course that NUST NET-Engineering draws on (Mathematics is 100 of the 200 MCQs). It breaks into 2 subtopics, and we hold 52 NET-pattern practice MCQs on it, each with a written explanation. Tap a subtopic below to practise just that.

Partial Fractions MCQs from the NET-pattern papers
Try each one before opening the answer. Each comes with a short explanation.
- Q1 · NUST NET Past Paper 07 · Partial Fractions
If (3x + 5)/((x + 1)(x + 2)) = A/(x + 1) + B/(x + 2), then A equals:
- A.1
- B.2
- C.3
- D.−1
Show answer
Answer: B. 2 — Cover-up at x = −1: A = (3(−1) + 5)/(−1 + 2) = 2/1 = 2.
- Q2 · NUST NET Past Paper 08 · Partial Fractions
If (2x + 3)/(x(x + 3)) = A/x + B/(x + 3), then A + B equals:
- A.2
- B.1
- C.4
- D.−1
Show answer
Answer: A. 2 — A = 1 (cover-up at x = 0), B = 1 (at x = −3), so A + B = 2.
- Q3 · NUST NET Past Paper 05 · Partial Fractions
If (5x − 1)/(x² − x − 2) = A/(x − 2) + B/(x + 1), then B equals:
- A.3
- B.−2
- C.1
- D.2
Show answer
Answer: D. 2 — x² − x − 2 = (x − 2)(x + 1). Cover-up at x = −1: B = (−6)/(−3) = 2.
