Answer 2

Answer:

Step-by-step explanation:

now,

       f(t)=t^2-pt-p-c(open bracket)

      f(t)=t^2-pt-(p+c).

    now,

alpha + beta= p                         and                         alpha*beta=-p-c

so,

   lhs= (alpha + 1) (beta + 1) = alpha*beta + alpha + beta + 1

        = -p-c+p+1

        =1-c.
