Let a plane $\displaystyle P$ pass through the point ($\displaystyle 3$, $\displaystyle 7$, -$\displaystyle 7$) and contain the line, $\displaystyle \frac{x-2}{-3}=\frac{y-3}{2}=\frac{z+2}{1}$. If distance of the plane P from the origin is d , then $\displaystyle \mathrm{d}^2$ is equal to \_\_\_\_.
