Hint: \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Factor \"x%5E3%2Bx%5E2-4x-4\" to get\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x%5E3%2Bx%5E2-4x-4\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28x%5E3%2Bx%5E2%29%2B%28-4x-4%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x%5E2%28x%2B1%29-4%28x%2B1%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28x%5E2-4%29%28x%2B1%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28x-2%29%28x%2B2%29%28x%2B1%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"x%5E3%2Bx%5E2-4x-4\" factors to \"%28x-2%29%28x%2B2%29%28x%2B1%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hopefully this will help you find the zeros. If not, let me know. Thanks.\r
