    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)
                   -----------
                            0
