Question

For the polynomial p (x). If p (7) = 0. then _____ is a factor of p (x).

A. x - 7 B. x + 7 C. 7x + 1 D. 7x - 1​

Answer 1

Answer:

A. x-7

Step-by-step explanation:

because x-7=0

x=7 and it's given that p(7) = 0

Answer 2

Answer:

A. x - 7

Step-by-step explanation:

p (x) = x - 7 = 0

p (7) = 7 - 7 = 0

p (7) = 0

Hence, x - 7 is a factor of p (x).
