1. ## division help?

I understand the basic steps to this question, but it is just not clicking. I know I should be simplifying the x's but the 4 is throwing me off.

Find the quotient when 2x^3 + 13x^2 + 17x - 12 is divided by x + 4?

Hello,

use long division:
Code:
  (2x^3 + 13x^2 + 17x - 12) ÷ (x + 4) = 2x^2 + 5x - 3
-(2x^3 +  8x^2)
-----------------
5x^2 + 17x
-(5x^2 + 20x)
--------------
-3x - 12
-(-3x - 12)
-----------
