If  $\alpha ,\beta$  are roots of the equation $\lambda (x^2-x)+x+5=0$  and if  ${\lambda }_1,{\lambda }_2$  are two values of  $\lambda$  for which the  roots $\alpha \&\beta$ are related by  $\frac{\alpha }{\beta }+\frac{\beta }{\alpha }=\frac{4}{5}$  and if the value of  $\frac{{\lambda }_1}{{\lambda }_2}+\frac{{\lambda }_2}{{\lambda }_1}$  is equal to
