Answer 1

Step-by-step explanation:

x²+x+1

we Have To Find the Value Of

$\frac{1}{ \alpha } + \frac{1}{ \beta }$

$\frac{1}{ \alpha } + \frac{1}{ \beta } = \frac{ \beta + \alpha }{ \alpha \beta }$

General Quadratic polynomial

${x}^{2} - ( \alpha + \beta )x + \alpha . \beta$

compare with given equation

$\alpha + \beta = - 1$

$\alpha . \beta = 1$

Adding The Value

$\frac{ \beta + \alpha }{ \alpha \beta } = \frac{ - 1}{1} = - 1$

Second case

${ \alpha }^{2} + { \beta }^{2} = { (\alpha + \beta )}^{2} - 2 \alpha \beta$

For Motivate Me leave A Thanks

${ (\alpha + \beta )}^{2} - 2 \alpha \beta = {( - 1)}^{2} - 2(1)$

$1 - 2 = - 1$
