The way my book has it is (1/2x^3)-x. Sorry for the confusion
No problem! It seems like you provided a mathematical expression: (1/2x^3) - x. If you're looking for an explanation of how to simplify or evaluate this expression, I can help with that.
To simplify this expression, you can start by distributing the negative sign to each term inside the parentheses. This gives us:
1/2x^3 - x = (1/2)x^3 - x
Next, we can combine like terms. In this case, there are no like terms, as the two terms have different variables and exponents.
So, the simplified expression would be (1/2)x^3 - x.
