There are several valid forms to indicate multiplication, although some are used specificially for functions that are not simple integers.
Multiply : the letter x, not as a variable (e.g. 3 x 5 = 15)
Dot Product : (e.g. 3 . 5) -- often represented in ASCII by the asterisk (3 * 5)
Multiple of variable (e.g. 2x, 3x)
Multiplication is also indicated by parentheses and brackets, indicating successive sequences of operations, such as
(3x-2)(x-1)
[x(x-2)](x-1)
