Yes it's just the answer has sine and cosines in it and I don't know how they got it

that's because your answer are complex conjugated solutions. Have you dealt with them before?

It's a bit hard to explain the nature of complex numbers and how they apply to Differential Equations in just one post, it's a rather big topic, but if you want, I can link you to Pauls Website where he deals with complex solutions.

just solve it using characterist equation; you should get expoential(like you always do) but with complex power; use euler idenity to get sin/cos

I was looking at it earlier under repeated roots and reduction order but it didn't help

Euler's identity? Yea we didn't cover that. I guess il try looking that up
