Question

alpha and beta are the zeroes of the polynomial x*x+6x +2 then find 1/alpha+1/betA, alpha - beta

Answer 1

$x \times x + 6x + 2 \\ {x}^{2} + 6x + 2 \\ a = 1 \\ b = 6 \\ c = 2 \\ \alpha + \beta = \frac{ - b}{a} \\ = \frac{ - 6}{1} \\ = - 6 \\ \alpha \beta = \frac{c}{a} \\ = \frac{2}{1} \\ = 2 \\ \frac{1}{ \alpha } + \frac{1}{ \beta } \\ = \frac{ \beta + \alpha }{ \alpha \beta } \\ = \frac{ - 6}{2} \\ = - 3$
