If $\"x=1\"$ is a zero of the polynomial $\"p%281%29=0\"$ ,
\n" ); document.write( "and if $\"p%28x%29+=ax%5E3-3%28a-1%29x-1\"$ , then
\n" ); document.write( " $\"a%2A1%5E3-3%28a-1%29%2A1-1=0\"$
\n" ); document.write( " $\"a%2A1-3%28a-1%29-1=0\"$
\n" ); document.write( " $\"a-3a%2B3-1=0\"$
\n" ); document.write( " $\"-2a%2B2=0\"$
\n" ); document.write( " $\"2=2a\"$
\n" ); document.write( " $\"2%2F2=a\"$
\n" ); document.write( " $\"highlight%28a=1%29\"$ \n" ); document.write( "
