1. The problem statement, all variables and given/known data Solve Q'+(1/(50+t))Q=1. 2. Relevant equations None. 3. The attempt at a solution This is my work: I know that the integrating factor is (1/(50+t)). e^integral of (1/(50+t))dt=e^ln abs(50+t)=50+t (50+t)Q'+Q=50+t Q(50+t)=50t+t^2+C Q=(50t+t^2+C)/(50+t) I got Q=(50t+t^2+C)/(50+t) as the answer. Am I right?
