Question

2) ( alpha operatorname{and} beta ) are ( x^{2}+7 x+7 )
( frac{1}{2}+frac{1}{beta}-2 alpha beta )
( x^{2}+7 x+7 )
[
begin{array}{l}x+beta=frac{-6}{a}=frac{-7}{1}=-7 x beta=frac{c}{a}=frac{7}{1}=7 frac{1}{2}+frac{1}{8}-2 alpha beta frac{2+p}{2 beta}-2 alpha beta =frac{-7}{7}-1-14=-15end{array}
