Let α and β be the roots of equation p x^2+ q x+ r =0, p ≠ 0. If p, q, r are in A.P. and 1/(α)+1/(β)=4, then the value of |α-β| is:
Let $\displaystyle \alpha$ and $\displaystyle \beta$ be the roots of equation $\displaystyle \mathrm{p} x^2+\mathrm{q} x+\mathrm{r}=0, \mathrm{p} \neq 0$. If p, q, r are in A.P. and $\displaystyle \frac{1}{\alpha}+\frac{1}{\beta}=4$, then the value of $\displaystyle |\alpha-\beta|$ is :
