Question

if alpha and beta are the zeroes of polynomial 2x^2+5x+1 then find the value of alpha+beta+alpha×beta​

Answer 1

Answer:

-2

Step-by-step explanation:

Here, in this polynomial,

a = 2

b = 5

c = 1

so, the sum of factors = -b/a

the product of factors = c/a

so (alpha + beta) + (alpha*beta) = (-b+c)/a

= -4/2

=-2.
