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

y'' + y' = 4t

2. Relevant equations

Use Variation of parameters!

3. The attempt at a solution

So I get homo of: c1 + c2 e^-(t)

From there I get a Wronskian of

-e^(-t)

Then I get variations 2t^2 and -4e^t(t-1)

Then get the answer of 2t^2 + 4t - 4

Btu its wrong :< uguu
