(-2x)-6

(2x)^-6

(2x)^-6

(1/2x)^6 =

1/64x^6

To simplify the expression (-2x) - 6, we need to perform the subtraction operation and simplify the expression as much as possible.

Here's how you can do it step by step:

Step 1: Distribute the -1 to -2x and -6:
(-2x) - 6 = -2x + (-6)

Step 2: Combine like terms by adding the coefficients of the x terms:
-2x + (-6) = -2x - 6

So, the simplified expression is -2x - 6.

Note: In this case, there are no like terms to combine further, so we cannot simplify it any more.
