Question

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

Answer 1

Answer:

Hey buddy

Step-by-step explanation:

p(x) = 2x² + 5x + 1

Sum of roots = -5/2

Product of roots = 1/2

Therefore substituting these values,

α + β +αβ

=(α + β) + αβ

= -5/2 + 1/2

= -4/2

= -2
