Best ResponseYou've already chosen the best response.1but your integrating factor is: \[e^{\lnx} = \frac{ 1 }{ x }\] I'm going to skip the work for the next few steps, you can use it as a reference to absolutely check your work, but you SHOULD see that you get product rule as a result. Therefore: \[[\frac{ 1 }{ x }y]'=1\] Next, take the integral: \[\int\limits [\frac{ 1 }{ x }y]'=  \int\limits dx = \frac{ 1 }{ x }y= x+C\] \[y = x^2+Cx\]

Best ResponseYou've already chosen the best response.0the equation should be \[\Large \frac{1}{x}y=\int\frac{1}{x} (1) dx\]

Best ResponseYou've already chosen the best response.0the differential equation is \[y'\frac{1}{x}y=1\] with integrating factor \(1/x\) the resulting equation is \[(1/x)y=\int(1/x)(1)dx\]
