Divive x^3 +27 by x+3

 

[stapel]

Either factor the sum of cubes, using the sum-of-cubes formula, and then cancel. Or else do the long division of x³ + 0x² + 0x + 27 by x + 3.

Which method are you using, and how far have you gotten?

Thank you.

I am using long division.

I am using long division.

So is the first step dividing by x^3 or x^2???

Why are you asking that?
The division is by x + 3.

Thanks. Could someone tell me if this is the correct answer.

x^2-3x-9 with no remainder.
