For each of the following polynomial, find and

p(x) = x⁴ – 2x² - x

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
