You can put this solution on YOUR website!
$\"%28x+%2B+2%29%5E2+=+7\"$
\n" ); document.write( " $\"sqrt%28%28x+%2B+2%29%5E2%29\"$ = + or - $\"sqrt%287%29\"$ Take the square root of both sides.
\n" ); document.write( "1. $\"x%2B2=sqrt%287%29\"$ Positive square root of the right hand side.
\n" ); document.write( "2. $\"x%2B2=-sqrt%287%29\"$ Negative square root of the right hand side.
\n" ); document.write( "Two solutions :
\n" ); document.write( " $\"x=sqrt%287%29-2\"$
\n" ); document.write( " $\"x=-sqrt%287%29-2\"$ \n" ); document.write( "
