Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I need some help factorizing the following:

[tex]\frac{g(x)-g(a)}{u(a)^2}=K(x,a)[/tex]

into [tex]A(a) X(x)[/tex]

ie I want to find [tex]A(a), X(x)[/tex] such that their product is the first equation. The reason I want to do this is because K(x,a) is a kernel and it would help a lot if somehow I could write it as:

[tex]K(x,a)=A(a) X(x)[/tex]

Finally, note that [tex]g'(a)=a/u(a)^2[/tex]

Any ideas?

Thanks in advance
