We have [ x^{2}-(k+6) x+2(2 k-1) ] we aro given that [ alpha+B=frac{1}{2} alpha beta rightarrow(1)[alpha, beta text { are roots of pol. }] ] we know [ begin{array}{l} alpha+beta=-b / a=k+6 text { and } quad alpha beta=c / a=2(2 k-1) end{array} ] Putting this in eq ( k+6=frac{2(2 k-1)}{2} ) ( 2 k-k=6+1 ) ( k=7 )
