Answer:
Answer: The value of α+β is -5.
Step-by-step explanation:
Since we have given that
x^2+5x+8x
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}=-5α+β=
a
−b
=
1
−5
=−5
Hence, the value of α+β is -5.
