Let $\displaystyle A$ be a point on the $\displaystyle x$-axis. Common tangents are drawn from $\displaystyle A$ to the curves $\displaystyle x^2+y^2=8$ and $\displaystyle y^2=16 x$. If one of these tangents touches the two curves at $\displaystyle Q$ and $\displaystyle R$, then $\displaystyle (Q R)^2$ is equal to
