You can put this solution on YOUR website!
if you have (5/x)+6-(/x)-6 then:
\n" ); document.write( "5/x-3/x+6-6
\n" ); document.write( "2/x+0
\n" ); document.write( "however if you have
\n" ); document.write( "5/(x+6)-3/(x-6)
\n" ); document.write( "you do not have the same denominators.
\n" ); document.write( "to get the same denomonators you need to multiply the first fraction by (x-6) & the second by (x+6).
\n" ); document.write( "[5(x-6)-3(x+6)]/(x+6)(x-6)
\n" ); document.write( "(5x-30-3x-18)/(x+6)(x-6)
\n" ); document.write( "(2x-48)/(x+6)(x-6)
\n" ); document.write( "2(x-24)/x^2-36
\n" ); document.write( "
\n" ); document.write( "
\n" );
