3a^2/a^2+a+1 2a/a-1 a^3/a^3-1
\n" ); document.write( "-----
\n" ); document.write( "Factor each denominator:
\n" ); document.write( "a^2+a+1 is not further factorable.
\n" ); document.write( "a-1 is not further factorable.
\n" ); document.write( "a^3-1 = (a-1)(a^2+a+1)
\n" ); document.write( "-------------------------
\n" ); document.write( "LCD = (a-1)(a^2+a+1)
\n" ); document.write( "====================
