joshua wants to know if x−5 is a factor of the polynomial p(x)=x^3−5x^2−x+5. joshua calculates p(5) and applies the factor theorem to conclude that x−5 is not a factor of p(x).

is josh's conclusion that x−5 is not a factor correct? why or why not?

a. yes, the remainder is −240, therefore x−5 is not a factor of p(x).

b. no, the remainder is −240, therefore x−5 is a factor of p(x).

c. yes, the remainder is 0, therefore x−5 is not a factor of p(x).

d. no, the remainder is 0, therefore x−5 is a factor of p(x).
