$\"-sqrt%284%29=-2\"$ but it also equals $\"-sqrt%284%29=-%28-2%29=2\"$ since $\"%28-2%29%28-2%29=4\"$
\n" ); document.write( "For $\"x=-2\"$
\n" ); document.write( "Real - Yes
\n" ); document.write( "Integer - Yes, whole numbers plus negatives of whole numbers
\n" ); document.write( "Rational - Yes, it's the ratio of two integers (2 and -1 as an example).
\n" ); document.write( "Irrational - No, it's rational, can't be both.
\n" ); document.write( "Whole - No, whole numbers are non-negative.
\n" ); document.write( "For $\"x=2\"$
\n" ); document.write( "Real - Yes
\n" ); document.write( "Integer - Yes
\n" ); document.write( "Rational - Yes, it's the ratio of two integers (2 and 1 as an example).
\n" ); document.write( "Irrational - No, it's rational, can't be both.
