8-146.

Let

*p*(*x*) =*x*^{3}– 3*x*^{2}– 7*x*+ 9. Homework Help ✎Read about the Remainder Theorem in the Math Notes box in Lesson 8.3.2. Then use the Remainder Theorem to determine

*p*(5).Use the Remainder Theorem to determine

*p*(1). What does your result tell you about the polynomial?

If there is no remainder then (*x* − 1) is a factor.
