You can put this solution on YOUR website!
$\"x%5E2-2x=-13\"$ take -13 to left changing sign
\n" ); document.write( " $\"x%5E2-2x%2B13=0\"$ a quadratic with no real solutions for x
\n" ); document.write( "It does not factor and using formula the discriminant:
\n" ); document.write( " $\"sqrt%28b%5E2-4ac%29\"$ = $\"sqrt%284-52%29\"$ is less than zero.
\n" ); document.write( "However if you are the person that sent me $\"x%5E2-2x=13\"$
\n" ); document.write( "by e-mail.This will give solutions.
\n" ); document.write( " $\"x%5E2-2x=13\"$ goes to
\n" ); document.write( " $\"x%5E2-2x-13=0\"$ using quadratic formula:
\n" ); document.write( " $\"x=%28-b%2B-sqrt%28b%5E2-4%2Aa%2Ac%29%29%2F%282%2Aa%29\"$ gives
\n" ); document.write( " $\"x=%282%2B-sqrt%2856%29%29%2F2\"$
\n" ); document.write( " $\"x=%281%2B-sqrt%2814%29%29\"$
\n" ); document.write( "x=4.7417 and
\n" ); document.write( "x=-2.7417
