Answer 1

$\tt \orange{sol:-}$

p(x) = x² + 7x + 7

comparing with general form of ax² + bx + c =0

•°• a = 1, b =7, c = 7

$\tt \red{now,}$

α + β = -b/a

•°• 1/α + 1/β = -a/b

= - 1/7

$\tt \red{And}$

α β = c/a

•°• α β = a/c

= 1/7

$\tt \red{now,}$

1/α + 1/β - 2 α β

= -1/7 - (2 × 1/7)

= -1/7 - 2/7

= (-1 -2)/7

= -3/7

1/α + 1/β - 2 α β = -3/7
