Let the function $\displaystyle f(x)=\left(x^2-1\right)\left|x^2-\mathrm{a} x+2\right|+\cos |x|$ be not differentiable at the two points $\displaystyle x=\alpha=2$ and $\displaystyle x=\beta$. Then the distance of the point $\displaystyle (\alpha, \beta)$ from the line $\displaystyle 12 x+5 y+10=0$ is equal to:
