ANSWER:
It would be 6x^3.
PRIOR NOTE:
For this question, it's slightly unclear regarding the formatting with it, but in here I'm going to assume that you've asked what is:
-2x * 3x * -x
when simplified. If it was something else, then the final answer would be different.
BACKGROUND:
To start, when multiplying two terms together, the variable will become squared or to the second power. For example:
2x * 2x = 4x^2
PROCESS:
With this question, it is asking for -2x * 3x * -x, though lets just start with the -2x * 3x part:
-2x * 3x = -6x^2
Now, finishing it off with the * -x part.
-6x^2 * -x = 6x^3
It goes to the third power, because now you have multiplied 3 x's together. The answer is also now positive since a negative * a negative = a positive.
With this, the final answer is 6x^3.
