Expert Answer
α and β are the zeroes of the polynomial f(x) = x2 - p(x + 1) - c  = x2 - px - p - c
Here a = 1 , b = - p and c = - p - c

α + β = -b/a = -(-p)/ 1 = p   ... (i) and αβ = c/a = -p - c / 1 = - p - c .... (ii)

We have (α + 1)(β +1) =0
→ αβ + α + β +1 = 0
→ - p - c + p + 1 = 0   ... from (i) and (ii)
→  c = 1
