Question and options
Amit and Alok attempted to solve a quadratic equation. Amit made a mistake in writing down the constant term and ended up with roots . Alok made a mistake in writing down coefficient of to get roots . The correct roots of the equation are:
- -4, -3
- 6, 1
- 4, 3
- -6, -1
Answer and explanation
Correct answer: B - 6, 1
Amit's error is only in the constant, so sum of roots 4+3 = 7 is correct; Alok's error is only in the x-coefficient, so product 3*2 = 6 is correct. Equation x^2 - 7x + 6 = 0 gives roots 6 and 1.
