You can put this solution on YOUR website!
well first off factor x^2-100 into (x+10)(x-10) you are left with
\r
\n" ); document.write( "\n" ); document.write( "x/((x+10)(x-10)) * (9x(x+10))/(x+3)
\r
\n" ); document.write( "\n" ); document.write( "the x+10's cancel leaving you with
\r
\n" ); document.write( "\n" ); document.write( "x/x-10 * 9x/x+3
\r
\n" ); document.write( "\n" ); document.write( "now just simplify
\r
\n" ); document.write( "\n" ); document.write( "9x(x)/(x-10)(x+3)
\n" ); document.write( "9x^2/(x^2+3x-10x-30)
\n" ); document.write( "9x^2/(x^2-7x-30) \n" ); document.write( "
\n" );
