Question

Alphya to the power -1+beta to the power-1

Answer 1

Answer:

for the zeroes of the quadratic equation

${ \alpha }^{ - 1} + { \beta }^{ - 1} = \frac{ - b}{c}$

Step-by-step explanation:

${ \alpha }^{ - 1} + { \beta }^{ - 1} = \frac{1}{ \alpha } + \frac{1}{ \beta } \\ = \frac{ \alpha + \beta }{ \alpha \beta } = \frac{ \frac{ - b}{a} }{ \frac{c}{a} } = \frac{ - b}{c}$
