You can put this solution on YOUR website!
$\"7x%5E3-28x=0\"$
\n" ); document.write( " $\"x%287x%5E2-28%29=0\"$
\n" ); document.write( "x=0 is one solution.
\n" ); document.write( "Next solve for
\n" ); document.write( " $\"7x%5E2-28=0\"$
\n" ); document.write( " $\"7x%5E2=28\"$
\n" ); document.write( " $\"x%5E2=4\"$
