You can put this solution on YOUR website!
(x-2)^2=13
\n" ); document.write( "find the square root of both sides
\n" ); document.write( "x - 2 = +/- $\"sqrt%2813%29\"$
\n" ); document.write( "add 2 to both sides
\n" ); document.write( "x = 2 + $\"sqrt%2813%29\"$ approx 5.61
\n" ); document.write( "and
\n" ); document.write( "x = 2 - $\"sqrt%2813%29\"$ approx -1.61
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check in original problem
\n" ); document.write( "(5.61-2)^2 = 13.03 because of rounding off
\n" ); document.write( "and
\n" ); document.write( "(-1.62-2)^2 = 13.03 \n" ); document.write( "

\n" );
