Question

4) If and are the zeros of a + bx +c then find the value of 1/alpha+ 1/ beta .​

Answer 1

Answer:

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