1. The problem statement, all variables and given/known data y' + y = t^2 , y(0) = 6, y'(0)= -6 2. Relevant equations 3. The attempt at a solution first i tried to seperate variables using y = ux but cant forward on and then i tried undetermined coeff. method. i found homogenous and particular solution but i am not sure about the solution because there is no need to use y'(0)=-6 and i really dont sure can i use this method for the first order ode.
