Your question isn't clear. There are no radicals.
\n" ); document.write( "f(x)=16-x^2
\n" ); document.write( "g(x)=4-x
\n" ); document.write( "f(x)-g(x)
\n" ); document.write( "=16-x^2-(4-x)
\n" ); document.write( "=16-x^2-4+x
\n" ); document.write( "=-x^2+x+12
\n" ); document.write( "=-(x^2-x-12)
\n" ); document.write( "=-(x-4)(x+3)
\n" ); document.write( ".
