Find all of the zeros of F(x) if F(x)=(x^2-4)^3 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "A zero of F(x) is a number k for which F(k) = 0.\r
\n" ); document.write( "\n" ); document.write( "We need to find values of x that cause (x^2-4)^3 = 0.\r
\n" ); document.write( "\n" ); document.write( "Note that x^2 - 4 = (x+2)*(x-2) so we need to find values of x such that
\n" ); document.write( "[(x+2)*(x-2)]^3 = 0\r
\n" ); document.write( "\n" ); document.write( "So zeros are where x-2 = 0 or x+2 = 0.\r
\n" ); document.write( "\n" ); document.write( "That is x = 2 or x = -2
\n" ); document.write( "
\n" );
