How do i solve the following equation?

u= L*(d^2i/dt)+ (1/c)*i r* (di/dt)L= 1,4 mF

C= 0,31 H

R= 1000 ohm

Well i have so far found the auxiliary equation:

0,31*r^2 + 1000*r + 1/(1,4*10^-6)=0

And the discriminant is found to be 114286. This makes the form of the solution:

Y=c1*e^r1x + c2*e^r2x

I have found the roots:

r1=-1067,64

r2= -2158,18

But I am stuck now and do not know what to do now.
