Question

if alpha and beta are the zeros of x2+5x+8 then the value of (alpha +beta) is​

Answer 1

Answer:

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.

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