Quadratic Equations — JAMB Mathematics Past Questions
Quadratic Equations is one topic inside the JAMB Mathematics syllabus, and drilling it on its own is usually faster than revising the whole subject again. Below: which JAMB years have examined it, then real Quadratic Equations questions with worked answers.
When JAMB examined Quadratic Equations
Quadratic Equations questions appear in our bank for the JAMB years below. This is taken from the questions themselves, not from a syllabus outline — so if a year is listed, this topic was genuinely examined that year.
A topic that keeps reappearing is a topic JAMB keeps testing. Newer years matter most, because question style drifts.

The roots of the quadratic equation 2x² − 5x + m = 0 are α and β, where m is a constant. Find (α² + β²) in terms of m.
- A 25/4 − m
- B 25 − m
- C 25/4 − 2m
- D 25 − 2m
Answer: A
Using identities: α + β = 5/2, αβ = m/2. Then α² + β² = (α + β)² − 2αβ = (25/4) − m.
