Find the complete general solution to the 2nd ODE:

9y'' + 9y' - 4y = 0

• Calculus-HELP PLZ !!!! -

9a^2+9a-4=0
(3a-1)(3a+4) = 0
a = -4/3,1/3

y = c1 e^(-4/3 x) + c2 e^(1/3 x)

Thank you so much Steve! I had gotten this far but what about solving for the "complete" general solution? That's where I get lost....

you got me.
We have found the general solution. Dunno what more you can come up with for a "complete" general solution.

Does your text explain the difference? Sounds bogus to me.
