3х(4-2х)-6-2х+4

To simplify the given expression, follow the order of operations (PEMDAS):

Step 1: Simplify within parentheses 4 - 2x = 2

Step 2: Distribute the 3 to the terms inside the parentheses 3 * 2 = 6

So, the expression becomes: 3(4 - 2x) - 6 - 2x + 4 = 6 - 6 - 2x - 2x + 4

Step 3: Combine like terms -6 - 6 = -12 -2x - 2x = -4x

Thus, the simplified expression is: -12 - 4x + 4
