In the first example, the result is x2 – 3x + 4 with no remainder. In the second example the
result is (x - 2) with remainder -5.
a. Is (x - 1) a factor of x3 – 4x2 + 7x - 4? Is
(x - 2) a factor of x2 - 9?
b. Divide x3 + 3x2 + 9x + 27 by (x + 3).
c. Write a description of the long division
algorithm and explain it to a friend.
