You can put this solution on YOUR website!
I guess you have this: $\"f%28x%29+=+%28x+%2B+4%29%5E3+%28x+-1%29\"$ , not $\"f%28x%29+=+%28x+%2B+4%293+%28x+-1%29\"$ \r
\n" ); document.write( "\n" ); document.write( " the zeroes:\r
\n" ); document.write( "\n" ); document.write( " $\"%28x+%2B+4%29%5E3=0\"$ or $\"+%28x+%2B+4%29%28x+%2B+4%29%28x+%2B+4%29+=0\"$ if $\"%28x+%2B+4%29+=0\"$ => $\"x=-4\"$ \r
\n" ); document.write( "\n" ); document.write( "since we have three times $\"x%2B4\"$ , means that the multiplicity of zero $\"x=-4\"$ is $\"3\"$ \r
\n" ); document.write( "\n" ); document.write( "and $\"%28x+-1%29=0\"$ if $\"x=1\"$ => we have it only ones and the multiplicity of zero $\"x=1\"$ is $\"1\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "as you can see, the graph cross the $\"x-axis\"$ at the zeros $\"x=1\"$ and $\"x=-4\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
