How do you bring the differential equation y' = (y+9x)^2 to a separable form? Thanks.

    1. The problem statement:

    y' = (y+9x)^2


    The attempt at a solution

    I just need to know how do you bring it into the separable form. Tell me numerically or just in words, I won't mind.
    Which method do I need to use?

    Thanks :smile:

    Change the dependent variable y to u with the substitution u = y + 9x.
