Ex 9.5, 3 For each of the differential equation given in Exercises 1 to 12, find the general solution : 𝑑𝑦/𝑑𝑥+𝑦/𝑥=𝑥^2 𝑑𝑦/𝑑𝑥+𝑦/𝑥=𝑥^2 Differential equation is of the form 𝑑𝑦/𝑑𝑥+𝑃𝑦=𝑄 where P = 𝟏/𝒙 and Q = x2 Finding integrating factor, I.F = e^∫1▒〖𝑝 𝑑𝑥〗 IF = e^∫1▒〖1/𝑥 𝑑𝑥〗 IF = e^log⁡𝑥 IF = x Solution is y (IF) = ∫1▒〖(𝑄×𝐼𝐹)𝑑𝑥+𝑐〗 yx = ∫1▒〖𝒙^𝟐×𝒙×𝒅𝒙+𝒄〗 yx = ∫1▒〖𝑥^3 𝑑𝑥+𝑐〗 yx = 𝑥^4/4+𝑐 xy = 𝒙^𝟒/𝟒+𝒄
