Answer 2

Answer: The value of α+β is -5.

Step-by-step explanation:

Since we have given that

$x^2+5x+8$

Let α and β are the zeroes of the above quadratic equation.

As we know the relation between zeroes and the coefficients of quadratic equation in the form of ax²+bx+c=0.

$\alpha +\beta =\frac{-b}{a}=\frac{-5}{1}=-5$

Hence, the value of α+β is -5.
