All real values except ones that make the denominator equal zero since division by zero is undefined.
\n" ); document.write( " $\"x%5E2-9=0\"$
\n" ); document.write( " $\"%28x-3%29%28x%2B3%29=0\"$
\n" ); document.write( "Two solutions:
\n" ); document.write( " $\"x-3=0\"$
\n" ); document.write( " $\"x=3\"$
\n" ); document.write( "and
\n" ); document.write( " $\"x%2B3=0\"$
\n" ); document.write( " $\"x=-3\"$
\n" ); document.write( "So all real values except $\"x=-3\"$ and $\"x=3\"$ .
