\n" ); document.write( "Sometimes you do and sometimes you don't.
\n" ); document.write( "If you end up with x^2 = 7 you need to \"extract the square root\"
\n" ); document.write( "if you are solving for x.
\n" ); document.write( "--------------------
\n" ); document.write( "But if you end up with x = 7 you don't have to \"extract the square root\".
