You can put this solution on YOUR website!
$\"7x%5E3-7x%5E2-x%2B1\"$ =
\n" ); document.write( " $\"7x%5E2%28x-1%29-%28x-1%29\"$ =
\n" ); document.write( " $\"%287x%5E2-1%29%28x-1%29\"$ =0
\n" ); document.write( "then x^2=1/7 or x=1
\n" ); document.write( "then solutions are $\"x=sqrt%281%2F7%29\"$ , $\"x=-sqrt%281%2F7%29\"$ and x=1 \n" ); document.write( "
