In the Maths Olympiad of 2020 at Animal Planet, two representatives from the donkey’s side, while solving a quadratic equation, committed the following mistakes.
(i) One of them made a mistake in the constant term and got the roots as 5 and 9.
(ii) Another one committed an error in the coefficient of x and he got the roots as 12 and 4.
But in the meantime, they realised that they are wrong and they managed to get it right jointly. Find the quadratic equation.

Understanding the Mistakes
In the scenario, two representatives from the donkey's side made errors while solving a quadratic equation. Let's analyze their mistakes:
First Representative's Error
- This representative obtained roots 5 and 9.
- The correct quadratic equation can be formed using the roots:
x² - (sum of roots)x + (product of roots) = 0
- Here, the sum of roots = 5 + 9 = 14 and the product of roots = 5 * 9 = 45.
- Therefore, the equation is:
x² - 14x + 45 = 0
Second Representative's Error
- This representative found roots 12 and 4.
- Similarly, using the roots, we can form the equation:
- Sum of roots = 12 + 4 = 16 and the product of roots = 12 * 4 = 48.
- Thus, the equation is:
x² - 16x + 48 = 0
Finding the Correct Equation
- The correct quadratic equation must align with both representatives' errors.
- We need to identify a quadratic equation that fits the correct roots, considering the mistakes made.
Verifying Option C
- Option C: x² - 14x + 48 = 0
- Roots of this equation can be calculated as follows:
- Sum = 14 (matches the first representative's sum)
- Product = 48 (matches the second representative's product)
- Therefore, the correct quadratic equation is indeed:
Final Answer
x² - 14x + 48 = 0 (Option C)

For 1st one,
Let the equation be x2 + ax + b = 0
Since roots are 5 and 9
∴ a = –14 and b = 45
For 2nd one,
Let the equation be x2 + px + q = 0
Since roots are 12 and 4.
∴ p = –16 and q = 48
Now, according to the question, b and p both are wrong. Therefore, the correct equation would be x2 –14x + 48 = 0
Let the equation be x2 + ax + b = 0
Since roots are 5 and 9
∴ a = –14 and b = 45
For 2nd one,
Let the equation be x2 + px + q = 0
Since roots are 12 and 4.
∴ p = –16 and q = 48
Now, according to the question, b and p both are wrong. Therefore, the correct equation would be x2 –14x + 48 = 0
