9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 (since the first three terms make a perfect square
= (3x - y - 9)(3x - y + 9) since the expression now is a difference of two squares.
(3x - y - 9)(3x - y + 9)

How do you factor x cubed plus 9x squared plus 2x plus 18?
Since the problem has 4 terms, first you factor x cubed plus 9x squared, then you factor 2x plus 18. So when you factor the first two term, you would get x sqaured (x plus 9). Then when you factor the last two terms and you get 2 (x plus 9). Ypure final answer would be (x squared plus 2)(x plus 9)
