\n" ); document.write( "f(x) = x^2 - 8x + 16 = 0
\n" ); document.write( "\"%28x-4%29%5E2+=0\"
\n" ); document.write( "(x-4) = 0
\n" ); document.write( "x = 4
\n" ); document.write( "-----------
\n" ); document.write( "x=4 is the minimum value of the function, f(x) = 0
\n" ); document.write( "For all other values, f(x) > 0
\n" ); document.write( "--> For all x, f(x) >= 0
\n" ); document.write( "--> All x
\n" ); document.write( "
\n" ); document.write( "
\n" );
