The sum of the roots of the equation, `ax^(2) + bx + c = 0` where `a,b` and `c` are rational and whose one of the roots is `4 - sqrt(5)` is

A

`8`

B

`-2sqrt(5)`

C

`2sqrt(5)`

D

`11`

Text Solution

Verified by Experts

The correct Answer is:
A
If one root `4-sqrt(5)` then the other root is `4+sqrt(5)` because the coefficient of the `x^(n)` term are rational .
