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