Question

if alpha and beta re the zeroes of the polynomial f(x)=xsquare+x+1, then 1/alpha+1/beta=

Answer 1

We have,

$\frac{1}{ \alpha } + \frac{1}{ \beta } \\ = \frac{ \alpha + \beta }{ \alpha \beta }$

We know,

$\alpha + \beta = - 1 \\ and \: \alpha \beta = 1$

Thus, the required answer stands;

$\frac{1}{ \alpha } + \frac{1}{ \beta } = \frac{ - 1}{1} = - 1$

HOPE THIS COULD HELP!!!
