Question

If 1 is a zero of the polynomial P(x), then:

• A. P(1) = 1
• B. P(1)=0
• C. P(1) = 1 and P(1) = 0
• D. P(1) = 2

Answer 1

Answer: (B), (D)

The correct options are
B

P(1)=0

D

P(1) = 2

A real number k is said to be a zero of a polynomial P(x) if P(k) = 0.
Therefore,
P(1) = 0.
P(2) - P(1) = P(2) - 0 = P(2)
