[?] Solve a recurrence relation?

I have been having trouble doing reccurence relation problems in my discrete structures class, this is one question I have been struggling on:

Solve the reccurence relation an = 3a(n-1)+10a(n-2) with initial terms a0 = 4 and a_1 = 1

I need some work to be shown so I can better understand the process! Thanks!

 RSolve[{a[n] == 3 a[n - 1] + 10 a[n - 2], a[0] == 4, a[1] == 1}, a[n], n]

 (*  {{a[n] -> 1/7 (19 (-2)^n + 9 5^n)}}  *)

For more info see here.
