\alpha

and

\beta

are the roots of the equation

a{x^2} + bx + c = 0

\alpha \beta = 3

and

a,\;b,\;c

are in AP, then

\alpha + \beta

is equal to

View answer and explanation

Correct option: D

- 2

Option D (

-2

) is correct because by using the given condition

\alpha\beta = 3

and the fact that a, b, c are in AP, we can find the value of

\alpha + \beta
