You can put this solution on YOUR website!
That means, replace x with 3x, and then simplify.\r
\n" ); document.write( "\n" ); document.write( "\"f%283x%29=%283x%29%2F%28%283x%29%5E2-4%29\"
\n" ); document.write( "Not much more you can do with it.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3x%2F%289x%5E2-4%29=%283x%29%2F%28%283x%2B2%29%283x-2%29%29\" which would be helpful in graghing since it shows two vertical asymptotes at x=-2/3 and x=2/3; and a root is at x=0.
