You can put this solution on YOUR website!
(x^2-4/x^2-x-6) / (x^2-x-2/x^2-8x+15) * (x^2-3x-10/x^2+3x+2) \r
\n" ); document.write( "\n" ); document.write( "[(x-2)(x+2)/(x-3)(x+2)] / [(x-2)(x+1)/(x-3)(x-5)] * [(x-5)(x+2)/(x+2)(x+1)]\r
\n" ); document.write( "\n" ); document.write( "Cancel where you can to get:\r
\n" ); document.write( "\n" ); document.write( "[ 1 / (x-3)] / [(x+1)/(x-3)(x-5)] * [(x-5)/(x+1)]\r
\n" ); document.write( "\n" ); document.write( "Invert the denominator to get:\r
\n" ); document.write( "\n" ); document.write( "[ 1 / (x-3)] * [(x-3)(x-5)/(x+1)] * [(x-5)/(x+1)]\r
\n" ); document.write( "\n" ); document.write( "Cancel again where you can to get:\r
\n" ); document.write( "\n" ); document.write( "[ 1 / 1] * [(x-5)/(x+1)] * [(x-5)/(x+1)]\r
\n" ); document.write( "\n" ); document.write( "= [(x-5)/(x+1)]^2\r
