You can put this solution on YOUR website!
\"f%28x%5E2+%2B1%29=x%5E4%2B5x%5E2%2B3\"\r
\n" ); document.write( "\n" ); document.write( "Let \"x+=+sqrt%28x-1%29\".\r
\n" ); document.write( "\n" ); document.write( "===> .\r
\n" ); document.write( "\n" ); document.write( "===> \"f%28x%5E2+-+1%29+=+%28x%5E2+-+1%29%5E2%2B3%2A%28x%5E2+-+1%29+-+1\",\r
\n" ); document.write( "\n" ); document.write( "do the rest...it will be good for you...
