Question

if alpha and beta are the zeroes of the polynomial 2x^2+7x+5 find the value of
1.alpha +beta+alpha×beta
2.1/alpha+1/beta
3.alpha/beta+beta/alpha​

Answer 1

Step-by-step explanation:

1. alpha +beeta =-7/2

alpha ×beeta = 5/2

2. 1/alpha +1/beeta =

=(alpha +beeta) /alpha beeta

= -7/2 / 5/2

-7/5
