Question 289099
The instruction tell me to factor completely given that the binomial following is the factor of the binomial. Please help i thought i had the hang of it it but guess not!!!
x3 + 2x2 - 5x - 6, x + 3

x + 3 --> x^3 + 2x^2 - 5x - 6 (x^2)
          x^3 + 3x^2
                -x^2 - 5x - 6 (-x)
                -x^2 - 3x
                     - 2x - 6 (-2)
                     - 2x - 6
                            0
(x + 3)(x^2 - x - 2)
(x + 3)(x - 2)(x + 1)   (x^2 + x - 2x - 2 by FOIL last 2 terms)
