Sample Solved Olympiad Problem
Here is an example of the high-order thinking skills (HOTS) questions included in the Class 10 Foundation Mathematics Sample Free pdf:
Problem: Quadratic Roots and Vieta’s Application
Question: If α and β are the zeroes of the quadratic polynomial f(x) = x2 − 5x + k such that α − β = 1, find the value of k.
Step-by-Step Solution:
- Apply Vieta’s Formulas: For f(x) = x2 − 5x + k, a = 1, b = −5, c = k.
Sum of zeroes: α + β = −(−5)/1 = 5.
Product of zeroes: αβ = k/1 = k. - Given Difference of Zeroes: α − β = 1.
- Use Algebraic Identity: (α + β)2 − (α − β)2 = 4αβ.
- Substitute Known Values: (5)2 − (1)2 = 4(k) ⇒ 25 − 1 = 4k ⇒ 24 = 4k.
- Solve for k: k = 24 / 4 = 6.
