On page 11 of Differential Equations Demystified (Krantz), there is an example that goes from this:
[tex]
e^{x^2} \cdot y^\prime + e^{x^2} \cdot 2xy = e^{x^2} \cdot x
[/tex]
To this:
[tex]
\left[ e^{x^2} \cdot y \right]^\prime = x \cdot e^{x^2}
[/tex]
Would someone give me a hint as to how they got from the first equation to the second?
thanks
