Divide the following: [x^3 - a^3]/(x - a) Is the numerator the difference of two perfect cubes? If so, how do I divide this fraction? The different variables confused me.

Do you know the difference of cubes: If you factor the numerator according to the above formula, you should see a common factor that'll cancel.
