You can put this solution on YOUR website!
we believe the numerator of second multiplier should be (21) not (2)

\n" ); document.write( ".
\n" ); document.write( "{ (x^2 +x-2) / (x^2 -7x) } * { (5x^2 -38x +21) / (x^2 +2x) }
\n" ); document.write( ".
\n" ); document.write( "factor
\n" ); document.write( ".
\n" ); document.write( "{ (x-1)(x+2)/ (x)(x-7)} * { (5x-3)(x-7) / x(x+2) }
\n" ); document.write( ".
\n" ); document.write( "simply by canceling opposing like terms
\n" ); document.write( ".
\n" ); document.write( "{ (x-1)(5x-3) } / x^2
\n" ); document.write( ".
\n" ); document.write( "check by allowing x=1,,both original and answer are zero
\n" ); document.write( "try allowing x=2,, both are 1.75,,,,ok
\n" ); document.write( "
\n" );
