Question

If alpha and beta are the zeros of the polynomials f(x) = x^2 + 5x + 8, then alpha + beta

Answer 1

Answer:

The value of alpha + beta is -5

Step-by-step explanation:

since we have given that

x²+5x+8

Let alpha and beta are the zeros of the above quadratic equation

As we know the relation between zeros and the coefficient of quadratic equation in the form of ax²+bx+c=0

alpha+beta=-b/a=-5/1=-5

Hence, the value of alpha+beta is -5.

Answer 2

Answer:

the value of alpha+beta is -5.
