Let α and β be the roots of the equation px² + qx + r = 0, p ≠ 0. If p, q, r are in A.P. and $\frac{1}{α}$ + $\frac{1}{β}$ = 4, then the value of |α − β| is:

Let −$\frac{π}{6}$ < θ < − $\frac{π}{12}$. Suppose α₁ and β₁ are the roots of the equation x² − 2x sec θ + 1 = 0 and α₂ and β₂ are the roots of the equation x² + 2x tan θ − 1 = 0. If α₁ > β₁ and α₂ > β₂, then α₁ + β₂ equals:
