If α,β are the roots of the equation x2+4x+p=0 where p=n∑r=0 nCr1+ – InterviewSolution

1.	If α,β are the roots of the equation x2+4x+p=0 where p=n∑r=0 nCr1+rt(1+nt)r⋅(−1)r, then \|α−β\| is
Answer» If $α, β$ are the roots of the equation $x^{2} + 4 x + p = 0$ where $p = n \sum r = 0^{n} C_{r} \frac{1 + r t}{(1 + n t)^{r}} \cdot (- 1)^{r}$ , then $\| α - β \|$ is
