(1/x-a)+(1/x+a)/(x/x-a)-(a/x+a)
\n" ); document.write( "---
\n" ); document.write( "The least common denominator of the denominator and the numerator are the same,
\n" ); document.write( "so they cancel. That leaves you with:
\n" ); document.write( "= [(x+a)+(x-a)]/[x(x+a)-a(x-a)]
\n" ); document.write( "---
\n" ); document.write( "= 2x/[x^2+a^2]
