I have to find all the real number solutions of:
\n" ); document.write( "x^3 - 216 = 0
\n" ); document.write( ":
\n" ); document.write( "This can be factored as the \"difference of cubes\" (-216 = -6^3)
\n" ); document.write( "(x - 6)(x^2 + 6x + 36)
\n" ); document.write( "the real solution: x = 6
\n" ); document.write( "
\n" );
