By solving, you first have to have an equation.
Assume the equation is (x-a)(x-b)...(x-z)=0, then the answer is simple: the problem has 26 roots, a, b, c, ...
The logic behind the solution is, if the product of N numbers is 0, at least one of the number has to be 0.
You have to assume that x here is just a dummy varibale, i.e., it can be replaced by, for example, "X", "Y", or anything not one of the 26 alphabets to avoid confustions.

Technically, that expression will be zero...
because it contains (x - x), which is always zero.
