2s^2 =(b^2 +c^2 )−(((h−k)/(h+k)))(b^2 −c^2 )                 −((2hk)/((h+k)^2 ))(a^2 )  please verify.
$$\mathrm{2}{s}^{\mathrm{2}} =\left({b}^{\mathrm{2}} +{c}^{\mathrm{2}} \right)−\left(\frac{{h}−{k}}{{h}+{k}}\right)\left({b}^{\mathrm{2}} −{c}^{\mathrm{2}} \right) \\ $$$$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:−\frac{\mathrm{2}{hk}}{\left({h}+{k}\right)^{\mathrm{2}} }\left({a}^{\mathrm{2}} \right) \\ $$$${please}\:{verify}. \\ $$

s^2 =((hb^2 +kc^2 )/a)−hk
$${s}^{\mathrm{2}} =\frac{{hb}^{\mathrm{2}} +{kc}^{\mathrm{2}} }{{a}}−{hk} \\ $$
