You can put this solution on YOUR website!
$\"x%5E2+%2B+4+=+40\"$
\n" ); document.write( "first what you want to do is get the x term by itself, you can do that by sybtracting 4 from both sides, then you get
\n" ); document.write( " $\"x%5E2+%2B+4-4+=+40-4\"$
\n" ); document.write( " $\"x%5E2+=+36\"$ in order to find x you have to take the square root of both sides
\n" ); document.write( " $\"sqrt%28x%5E2%29+=+sqrt%2836%29\"$
\n" ); document.write( "your solutions are
\n" ); document.write( " $\"x=6\"$ or $\"x=-6\"$
\n" ); document.write( "The reason you have two solutions is because $\"6%2A6=36\"$ and $\"-6%2A%28-6%29=36\"$ \n" ); document.write( "

\n" );
