Answer 2

It seems like you have provided an expression that consists of variables and mathematical operations. Let's break it down step by step:

The expression you provided is: 8ab - 2b³ + ac - bc + 2a - 2b

To simplify this expression, we can combine like terms. Like terms are terms that have the same variables raised to the same powers.

In your expression, we have the following terms:

- 8ab - This term consists of the variables "a" and "b" multiplied together. - -2b³ - This term consists of the variable "b" raised to the power of 3. - ac - This term consists of the variables "a" and "c" multiplied together. - -bc - This term consists of the variables "b" and "c" multiplied together. - 2a - This term consists of the variable "a". - -2b - This term consists of the variable "b".

Now, let's group the like terms together:

- 8ab - 2b³ + ac - bc + 2a - 2b can be rearranged as: - 8ab + ac - 2b³ - bc + 2a - 2b

We can now combine the like terms:

- 8ab + ac - 2b³ - bc + 2a - 2b remains as it is, because there are no like terms that can be combined further.

So, the simplified form of the expression 8ab - 2b³ + ac - bc + 2a - 2b is 8ab + ac - 2b³ - bc + 2a - 2b.

I hope this helps! Let me know if you have any further questions.
