Subtract. [ (x – 7) / (x^2 – 9) ] – [ 3x / (9 – x^2) ]
\n" ); document.write( "------------------------------
\n" ); document.write( "Modify the problem:\r
\n" ); document.write( "\n" ); document.write( "= [ (x – 7) / (x^2 – 9) ] + [ 3x /(x^2-9) ]
\n" ); document.write( "---
\n" ); document.write( "Since the denominators are not the same, combine the numerators:
\n" ); document.write( "= [(4x-7)/(x^2-9)]
\n" ); document.write( "==========================
