Question

1) If alpha and Beta are two zeroes of the polynomial 2x² + 3x +5, then find the value of 1/alpha+1/beta​

Answer 1

Step-by-step explanation:

p(x)=2x² + 3x +5

$\alpha + \beta = \frac{ - b}{a} = \frac{ - 3}{2} \\ \alpha \beta = \frac{c}{a} = \frac{5}{2} \\ \frac{1}{ \alpha } + \frac{1}{ \beta } = \frac{ \alpha + \beta }{ \alpha \beta } \\ = \frac{ - 3}{2} \div \frac{5}{2} \\ = \frac{ - 3}{5}$

Answer 2

Answer:

$- \frac{3}{5}$
