Question

x^2+6x+2 ke shunyank α,β hain to α/β+ β/ α ka maan gyat karna hain in hindi

Answer 1

Step-by-step explanation:

f(x) = x²+6x+2

given roots :

$\alpha \: and \: \beta$

Relationship b/w zeroes and their coefficients:

$\alpha + \beta = - \frac{b}{a} \\ \: \: \: \: \: \: \: \: \: = \frac{ - 6}{1} \\ \: \: = - 6 \\ \\ \alpha \beta = \frac{c}{a} \\ \: \: \: = \frac{2}{1}$

Acq,

$\frac{1}{ \alpha } + \frac{1}{ \beta } = \frac{ \beta + \alpha }{ \alpha \beta } \\ \: \: \: \: \: \: \: = \frac{ - 6}{2} = - 3$
