Which of the following are roots of the polynomial?
\n" ); document.write( "How do i find these?\r
\n" ); document.write( "\n" ); document.write( "x3 - x2 - 5x - 3
\n" ); document.write( "------------
\n" ); document.write( "Nothing followed.
\n" ); document.write( "----
\n" ); document.write( "Try the integers first, 3 & -3
\n" ); document.write( "---
\n" ); document.write( " $\"f%28x%29+=+x%5E3+-+x%5E2+-+5x+-+3\"$
\n" ); document.write( " $\"f%283%29+=+27+-+9+-+15+-+3+=+0\"$
\n" ); document.write( "That's one.
\n" ); document.write( "Divide $\"x%5E3+-+x%5E2+-+5x+-+3\"$ by (x-3)
\n" ); document.write( "--> $\"x%5E2+%2B+2x+%2B+1+=+%28x%2B1%29%5E2\"$
\n" ); document.write( "---------
\n" ); document.write( "x = -1, -1, 3
\n" ); document.write( " \n" ); document.write( "

\n" );
