Solve the following differential equations :

Formula:-


(i)∫[f(x) + f’(x)]exdx = f(x)ex + c


(ii) If a differential equation is ,


then y(I.F) = ∫Q.(I.F)dx + c, where I.F = e∫Pdx


(iii) ∫dx = x + c





Given:



This is a linear differential equation, comparing it with





I.F = e∫Pdx



= e–log|x|



Solution of the equation is given by


y(I.F) = ∫Q.(I.F)dx + c




using formula(v)



y = ex + cx
