Answer 1

Typo free question:

Determine whether the binomial is a factor of F(x).

Answer:

Yes.

Step-by-step explanation:

Method one: evaluate F(5). If F(5) is zero then x-5 is a factor.

Method two: use long polynomial division to divide F(x) by (x-5). If the remainder is zero then (x-5) is a factor.
