Answer 2

Answer:

$\frac{1}{ \alpha } + \frac{1}{ \beta } \\ \\ here \: \\ a = 1 \\ b = 1 \\ c = - 2 \\ \\ \alpha + \beta = \frac{ - b}{a} \\ = \alpha \beta = \frac{c}{a} \\ \\ \frac{1}{ \alpha } + \frac{1}{ \beta } = \frac{ \beta + \alpha }{ \alpha \beta } \\ = \frac{ - 1}{ - 2} \\ \\ = \frac{1}{2} \\ \\ \\ hope \: that \: it \: will \: help \: u$
