Best ResponseYou've already chosen the best response.0well, lets start by dividing off that 2 x' + x/2 = 3t^2/2 we want to determine an e^rt that will allow us to turn this into a product rule; e^t/2 should work e^(t/2) x' +e^(t/2) x/2 = e^(t/2)3t^2/2 when we integrate both sides we get \[e^{t/2}x= \int e^{t/2}\frac{3t^2}{2}dt\]

Best ResponseYou've already chosen the best response.0forgot the +C at the end:) this gives us \[e^{t/2}x=3e^{t/2}(t^24t+8)+C\] divide off the e^{t/2} \[x=3(t^24t+8)+Ce^{t/2}\]

Best ResponseYou've already chosen the best response.1I did it the 'integrating factor' way too, just because I was curious... fair bit of work doing that integral..
