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)
