A first order linear equation in the form y′+p(x)y=f(x)y′+p(x)y=f(x) can be solved by finding an integrating factor μ(x)=exp(∫p(x)dx)μ(x)=exp⁡(∫p(x)dx) (1) Given the equation xy′+(1+3x)y=10xe−3xxy′+(1+3x)y=10xe −3x find μ(x)=μ(x)= (2) Then find an explicit general solution with arbitrary constant CC.
