I am trying to get a symbolic expression which involves taking an equation and multipying it with its complex conjugate.

Mathematica however does not realise the fact that all of the variables in the expression are real, and simply doesn't evaluate them i.e. "x . Conjugate[x]" gives the result -> x Conjugate[x] even though the result is simply x^2.

Is there a way of defining right from the outset that x is always Real???
