Solve:
\n" ); document.write( " $\"x%5E2-80+=+0\"$ First add 80 to both sides of the equation.
\n" ); document.write( " $\"x%5E2+=+80\"$ Now take the square root of both sides.
\n" ); document.write( " $\"x+=+sqrt%2880%29\"$ or $\"x+=+-sqrt%2880%29\"$ Simplify.\r
\n" ); document.write( "\n" ); document.write( " $\"sqrt%2880%29+=+sqrt%285%2A16%29\"$ = $\"4sqrt%285%29\"$
\n" ); document.write( "So:
\n" ); document.write( " $\"x+=+4sqrt%285%29\"$ or $\"x+=+-4sqrt%285%29\"$ \n" ); document.write( "

\n" );
