-3*6+2К*(-2)

To simplify the expression \(-3 \times 6 + 2K \times (-2)\), we can follow these steps:

1. Calculate \(-3 \times 6\): \[ -3 \times 6 = -18 \]

2. Calculate \(2K \times (-2)\): \[ 2K \times (-2) = -4K \]

3. Combine the results: \[ -18 - 4K \]

So, the simplified expression is: \[ -18 - 4K \]
