Solve x(ln x)^2*y'=-4(ln x)^2+y*ln x+y^2 explicitly.

OpenStudy (idealist10):

The answer I got is...\[y=\frac{ 2lnx(C+(\ln x)^{4^{}}) }{ C-(\ln x)^4 }\]

OpenStudy (idealist10):

But the answer in the book is...\[y=\frac{ 2\ln x(1+C(\ln x)^4) }{ 1-C(\ln x)^4 }\]

OpenStudy (idealist10):

Which answer is right? My answer or the answer in the book?

They ae the same. Factor a C out of the numerator AND denominator, cancel them out. You end up with some new constants 1/c, yes? Just call those something else, c1 :)

OpenStudy (idealist10):

So my answer is correct, right?

zepdrix (zepdrix):

If the book answer is correct, then yes yours is also correct :)
