If $\"x%5E2-x%2B1=0\"$ is a factor of $\"ax%5E3%2Bbx%5E2%2Bcx%2Bd=0\"$ then
\n" ); document.write( "a) $\"d+-+a+=+b+-+2c\"$
\n" ); document.write( "b) $\"a+-+d+=+b+%2B+2c\"$
\n" ); document.write( "c) $\"a+%2B+d+=+b+-+2c\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x2-x%2B1=0\"$ ЕЕЕ $\"a=0\"$ , $\"+b=1\"$ , $\"c=-1\"$ , $\"d=1\"$ \r
\n" ); document.write( "\n" ); document.write( "Then:\r
\n" ); document.write( "\n" ); document.write( "a) $\"1+-+0=+1+%962%28-1%29\"$
\n" ); document.write( " $\"1=1%2B2\"$
\n" ); document.write( " $\"1=3\"$ .......... $\"1\"$ is not equal to $\"3\"$ \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "b) $\"0+-1+=+1+%2B+2%28-1%29\"$
\n" ); document.write( " $\"-1+=+1+%962\"$
\n" ); document.write( " $\"-1+=-1\"$ ЕЕЕЕЕthis is your answer\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "c) $\"0+%2B+1=+1+-2%28-1%29\"$
