If alpha and beta are the zeros of x^(2...

If` alpha and beta` are the zeros of ` x^(2) + 5x + 8` then the value of `(alpha+beta)` is

A

5

B

`-5`

C

8

D

`-8`

Verified by Experts

The correct Answer is:

B

For ` ax^(2) + bx+c`, we have `alpha+beta = (-b)/a.`
For `x^(2) + 5x +8`, we have `alpha +beta =- 5.`
