Answer :

To find: p (1)

Put x = 1 in the given polynomial


p (1) = (1)4 – 2 × (1)2 – 1


= 1 – 2 – 1


p (1) = -2


To find: p (0)


Put x = 0 in the given polynomial


p (0) = 0 – 0 – 1


p (0) = -1


To find: p (-2)


Put x = -2 in the given polynomial


p (-2) = (-2)4 – 2 × (-2)2 – 1


= 16 – 2 × 4 – 1


= 16 -8 -1


= 7
