Question about a differential problem

  1. Sep 2, 2008 #1
    1. The problem statement, all variables and given/known data
    C1e^2x + C2Xe^2x is what i need to derive.

    2. Relevant equations

    3. The attempt at a solution my teacher got this 2C1e^2x + C2e^2x + 2C2Xe^2x. when i derived i got 2C1e^2x + 2C2e^2x. can someone tell me which is correct and if i am wrong, what should be done to correct it.

    Your teacher is right. For the second term you need to use the product rule. It's the product of two functions of x.
