Simplify (15x2 - 24x 9) : (3x - 3)

If you would like to simplify (15x^2 - 24x + 9) / (3x - 3), you can do this using the following steps:

15x^2 - 24x + 9 = 3 * (5x - 3) * (x - 1)

3x - 3 = 3 * (x - 1)

(15x^2 - 24x + 9) / (3x - 3) = 3 * (5x - 3) * (x - 1) / 3 * (x - 1) = 5x - 3 for x! = 1

The correct result would be 5x - 3 for x! = 1.
