Question

if alpha and beta are the zeros of p of x is equal to x square + x - 1 then find 1/alpha+1/beta​

Answer 1

Answer:

which alpha H¥DRA | ALPHA or STR ALPHA

Answer 2

Answer:

$p(x) = {x}^{2} + x - 1 \\ if \: \alpha \: and \: \beta are \: roots \: of \: \: p(x)\\ \alpha + \beta = \frac{ - 1}{1} = - 1 \: and \: \alpha \beta = - 1$

Now

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