Question

15.If α , β are the zeroes of the polynomial f(x) = x² -p(x+1) -c such that(α+1) (β+1) = 0, then c= ​

Answer 1

Answer:

Here

alpha + beta= p

alpha. beta = -p-c

Now (alpha +1).(beta+1) =0

=> 1-c=0

=> c=1

Answer 2

Answer:

alpha + beta= p

alpha. beta = -p-c

Now (alpha +1).(beta+1) =0

=> 1-c=0

=> c=1
