Homework Help: Second Order Differential Equation problem

  1. Jul 2, 2013 #1
    I have a small problem in solving a Second Order Linear Constant Coefficient Differential Equation.
    Please see the attached image. I understand upto the point above the arrow. What I don't understand is how he got

    dy/dx = 9
