1. Find the quotient and remainder when p(x) = (3x^3 - 2x^2 - 5 + 7x) is divided by d(x) = x + 3 using synthetic division.
 
Answer:
 
Quotient =
 
Remainder =
 
2. Prove that (x - 1) is a factor of x^3 - 7x^2 + 13x - 7.
 
Answer:
 
Sum of coefficients of
 powers of x including the constant =
.
 
Since
, then (x - 1) is a factor of x^3 - 7x^2 + 13x - 7.
 
Hence, we proved.
