ECZ 2015 · O-Level Paper 1 — Quadratic Equations
Solve the equation 2y² = 13y.
- A. y = 6.5 only
- B. y = 0 or y = 6.5
- C. y = 0 or y = −6.5
- D. y = ±6.5
Verified working — step 1
2y² − 13y = 0 ⇒ y(2y − 13) = 0 ⇒ y = 0 or y = 132= …The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
