If the mean and variance of the data 65,68,58,44,48,45,60, α, β, 60 where α> β, are 56 and 66.2 respectively, then α^2+β^2 is equal to ____.

If the mean and variance of the data $\displaystyle 65,68,58,44,48,45,60, \alpha, \beta, 60$ where $\displaystyle \alpha>$ $\displaystyle \beta$, are $\displaystyle 56$ and $\displaystyle 66.2$ respectively, then $\displaystyle \alpha^2+\beta^2$ is equal to $\displaystyle \_\_\_\_$.
