(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

9y'' + 6y' + y = 0

r^2 + 6r + 1

( -6 +/- root 36 - 36 ) / 18

lamda = -6/18 = -(2/9)

mu = 0

(this is the part im unsure about, because if i end up with a zero under the root, then does this make the final equation into this:

y = c_1*cos(0*x) + c_2*sin(0*x)

thanks for any help.
