What is 6x 11 12 5x?

The expression "6x 11 12 5x" seems to be missing some operators for clarity, but if interpreted as a multiplication of the coefficients and variables, it could be understood as (6x \times 11 \times 12 \times 5x). This would equal (360x^2), since (6 \times 11 \times 12 \times 5 = 360) and (x \times x = x^2). If you meant something different, please provide more context!
