Try each one before opening the answer. Each comes with a short explanation.
- Q1 · NUST NET Past Paper 07 · Quadratic Equations
For the quadratic equation ax² + bx + c = 0, the product of the roots is:
- A.c/a
- B.−b/a
- C.b/a
- D.−c/a
Show answer
Answer: A. c/a — Product of roots = c/a.
- Q2 · NUST NET Past Paper 08 · Quadratic Equations
The roots of x² − 5x + 6 = 0 are:
- A.1 and 6
- B.−2 and −3
- C.2 and 3
- D.−1 and 6
Show answer
Answer: C. 2 and 3 — x² − 5x + 6 = (x − 2)(x − 3), so x = 2 or 3.
- Q3 · NUST NET Past Paper 05 · Quadratic Equations
If α and β are the roots of x² − 7x + 10 = 0, then αβ equals:
- A.10
- B.7
- C.−7
- D.−10
Show answer
Answer: A. 10 — αβ = c/a = 10/1 = 10.
