Sachin and Rahul attempted to solve a quadratic equation. Sachin made a mistake in writing down the constant term and ended up in roots (4,3). Rahul made a mistake in writing down coefficient of x to get roots (3, 2). The correct roots of equation are:

A

4, 3

B

`-6, -1`

C

`-4, -3`

D

6, 1

Text Solution

Verified by Experts

The correct Answer is:
D
Let the equation be `ax^(2) + bx + c = 0`. Then, `-(b)/(a) = 7 and (c)/(a) = 6`
So, the equation is `x^(2) - 7x + 6 = 0` and its roots are 1 and 6.
