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

determine the particular solution for the differential equation 2x^double prime+x=3t^2

2. Relevant equations

3. The attempt at a solution

since F(t)=3t^2 I used At^2+Bt+C and the first derivative is 2A+B

plugging back in I get

At^2+(4A+B)t+(2B+C)=3t^2

is this correct?

how do I solve for the variables?
