Homework Statement
[tex]\int[/tex] dx/(x4 + 16)
Homework Equations
Hint: With a>0, x4 + a2 = (x2 + [tex]\sqrt{}2a[/tex]x + a)(x2 - [tex]\sqrt{}2a[/tex]x + a)
The Attempt at a Solution
I've plugged this into the equation, which leaves me with:
[tex]\int[/tex] dx/[(x2 + [tex]\sqrt{}2a[/tex]x + a)(x2 - [tex]\sqrt{}2a[/tex]x + a)]
But now I am sooooo confused! Where do I go from here? This hint does not seem so helpful... Please help!
