Question

Find the zerose of the polynomial x2+5x+8

Answer 1

Step-by-step explanation:

Answer: The value of α+β is -5.

Step-by-step explanation:

Since we have given that

x^2+5x+8x2+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
