(x3 − 4x2 − 12x + 9) is divided by (x + 2)?
Expand the following: (x^3-4 x^2-12 x+9)/(x+2) (x^3-4 x^2-12 x+9)/(x+2) = 9/(x+2)-(12 x)/(x+2)-(4 x^2)/(x+2)+x^3/(x+2): Answer: | | 9/(x+2)-(12x)/(x+2)-(4x^2)/(x+2)+x^3/(x+2)
x^2 - 6x
x + 2 [ x^3 − 4x^2 − 12x + 9 ]
x^2 + 2x^2
------------------------------------
- 6x^2 - 12x
-6x^2 - 12x
-----------------------
9
So...the result is x^2 - 6x Remainder 9 / [ x + 2 ]
