Question

If a and b are zeroes of x²+5x+8 the value of alpa +beta is _____

Answer 1

Answer:

-5

Step-by-step explanation:

Let a = alpha and b = beta

alpha + beta= -Coefficient of x/ Coefficient for x^2

= -5/1

=-5

Answer 2

Step-by-step explanation:

we know that

Alpha+Beta = - b/a

As coefficient a= 1, b= -5 & c= 8

Therefore Alpha+Beta = - 5
