What is the remainder when (x3 โˆ’ 7×2 โˆ’ 18x + 42) is divided by (x + 3)?

THIS IS THE BEST ANSWER ๐Ÿ‘‡

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
