Homework Statement
The curves are:
[tex] y = \frac{x^{4}}{x^{2}+1} [/tex]
and
[tex] y = \frac{1}{x^{2}+1} [/tex]
The Attempt at a Solution
So again I assume that:
[tex] \frac {x^{4}}{x^{2}+1} = \frac {1}{x^{2}+1} [/tex]
and then cross multiply:
[tex] (x^{2}+1) = x^{4}(x^{2}+1) [/tex]
not really sure at this point if i should distribute the x^4 but if i do it looks like so:
[tex] (x^{2}+1) = (x^{6}+x^{4}) [/tex]
so:
[tex] (x^{2}+1)-(x^{6}+x^{4}) = 0 [/tex]
and I am not really sure what to do at this point, I do have a polynomial if I do the subtraction which is:
[tex] -x^{6}-x^{4}+x^{2}+1 = 0 [/tex]
but I don't know how to factor it...
thanks guys!
