Question

if a,b are the zeroes of polynomial xsquare+x+1then the value of 1/alpha +1/beta is?​

Answer 1

it will be in negative i believe

Answer 2

Answer:

x

Step-by-step explanation:

$\frac{1}{a} + \frac{1}{b}$

$= \frac{a + b} {ab}$

$now \: (a + b) \: is \: sum \: of \: roots \: = x$

$and \: (ab) \: is \: product \: of \: roots \: = 1$

$substituting \: these \: vale \: we \: get$

$\frac{x}{1} = x$
