$\"P%28x%29+=+%28x%5E2+-+25%29%28x+%2B+1%29%5E3\"$
\n" ); document.write( "The first bracket factorises to give $\"%28x%2B5%29%28x-5%29\"$
\n" ); document.write( " $\"P%28x%29+=+%28x%2B5%29%28x-5%29%28x+%2B+1%29%5E3\"$
\n" ); document.write( "So the zeroes are -5 (once), +5 (once), and -1 (three times) \n" ); document.write( "

\n" );
