$\"x%5E2-7x=5\"$
\n" ); document.write( "First make one side of the equation zero. Subtracting 5 from each side:
\n" ); document.write( " $\"x%5E2-7x-5=0\"$

\n" ); document.write( "Now use the Quadratic Formula:
\n" ); document.write( " $\"x+=+%28-%28-7%29%2B-sqrt%28%28-7%29%5E2-4%281%29%28-5%29%29%29%2F2%281%29\"$

\n" ); document.write( " $\"x+=+%287%2B-sqrt%2869%29%29%2F2\"$
\n" ); document.write( "which is short for:
\n" ); document.write( " $\"x+=+%287%2Bsqrt%2869%29%29%2F2\"$ or $\"x+=+%287-sqrt%2869%29%29%2F2\"$ \n" ); document.write( "

\n" );
