Ram and Shyam solve a quadratic equation. Ram makes a mistake in the constant term and finds the roots as . Shyam makes a mistake in the co-efficient of and gets the roots as . The correct roots are:
- A1, 3
- B-1, 3
- C-1, -3
- D1, -1
Solution & Step-by-step Explanation
Let the standard quadratic equation be written as:
1. Ram's calculation:
* Ram makes a mistake in the constant term, which means his coefficient of (and thus his Sum of roots) is correct.
2. Shyam's calculation:
* Shyam makes a mistake in the coefficient of , which means his constant term (and thus his Product of roots) is correct.
3. Forming the correct equation:
Substituting the correct sum and product back into the standard quadratic form:
Factoring the quadratic equation:
Thus, the correct roots are and .
