You can put this solution on YOUR website!
What if you did a substitution,
\n" ); document.write( " $\"u%5E2-7u%2B10=0\"$
\n" ); document.write( "How would you find the zeros??
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "You can factor,
\n" ); document.write( " $\"x%5E4-7x%5E2%2B10=0\"$
\n" ); document.write( " $\"%28x%5E2-2%29%28x%5E2-5%29=0\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( " $\"x%5E2-2=0\"$
\n" ); document.write( " $\"x%5E2=2\"$
\n" ); document.write( " $\"highlight%28x=0+%2B-+sqrt%282%29%29\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( " $\"x%5E2-5=0\"$
\n" ); document.write( " $\"x%5E2=5\"$
\n" ); document.write( " $\"highlight%28x=0+%2B-+sqrt%285%29%29\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
