What is the remainder when (x3 − 7x2 − 18x + 42) is divided by (x + 3)?

6

Step-by-step explanation:

You can use Ruffini's rule to divide x^3 − 7x^2 − 18^x + 42 by x + 3 as follows :

   | 1   -7   -18   | 42

-3 |     -3    30  | -36

   | 1   -10   12   |  6

Then (x^3 − 7x^2 − 18^x + 42) : (x + 3) = (x^2 - 10x +12)*(x + 3) + 6
