$\"f%28x%29=2%28x%2B2%29%28x-4%29%5E4\"$
\n" ); document.write( "That function is zero when and only when one of its factors is zero.
\n" ); document.write( " $\"2\"$ is never zero.
\n" ); document.write( " $\"x%2B2=0\"$ ---> $\"highlight%28x=-2%29\"$
\n" ); document.write( " $\"%28x-4%29%5E4=0\"$ ---> $\"highlight%28x=4%29\"$
\n" ); document.write( "The zeros of $\"f%28x%29=2%28x%2B2%29%28x-4%29%5E4\"$ are
\n" ); document.write( " $\"highlight%28x=-2%29\"$ and $\"highlight%28x=4%29\"$ . \n" ); document.write( "

\n" );
