Q2 of 84 Page 53

For each of the following polynomial, find and

p(y) = y2 – 2y + 5

To find: p (1)

Put x = 1 in the given polynomial


p (1) = (1)2 – 2 × 1 + 5


= 1 – 2 + 5


= -1 + 5


= 4


To find: p (0)


Put x = 0 in the given polynomial


p (0) = 0 – 0 + 5


= 5


To find: p (-2)


Put x = -2 in the given polynomial


p (-2) = (-2)2 – 2 × (-2) + 5


= 4 + 4 + 5


p (-2) = 13
