You can put this solution on YOUR website!
It depends !
\n" ); document.write( "Does it mean
\n" ); document.write( "z^2-(64/8)-z
\n" ); document.write( "\"z%5E2-%2864%2F8%29-z\"
\n" ); document.write( "If that is the expression then yes you did it right.
\n" ); document.write( "`
\n" ); document.write( "or (z^2-64)/(8-z)
\n" ); document.write( "\"%28z%5E2-64%29%2F%288-z%29\"
\n" ); document.write( "if this is the expression (most likely) then no.
\n" ); document.write( "It can be factored into
\n" ); document.write( "(z-8)(z+8)/-(z-8)\r
\n" ); document.write( "\n" ); document.write( "\"%28z-8%29%28z%2B8%29%2F%28-1%2A%28z-8%29%29\"
\n" ); document.write( "-(z+8)
\n" ); document.write( "-z-8\r
\n" ); document.write( "\n" ); document.write( "Now you see why parentheses are so important.
\n" ); document.write( "Use them freely they are free\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
