Final answer:
To perform the indicated operation and simplify the result, distribute 3x^2 to each term inside the parentheses and combine like terms.
Step-by-step explanation:
To perform the indicated operation and simplify the result, we multiply the terms using the distributive property. First, distribute 3x^2 to each term inside the parentheses:
- 3x^2 * 3x = 9x^3
- 3x^2 * (-6/x) = -18x
The simplified result is 9x^3 - 18x.
