Simplify.
\[
3 x\left(x^{2}-2\right)-2\left(x-3 x^{2}\right)
\]
Final Answer: \(\boxed{x(3x^2 + 6x - 8)}\)
Step 1 :Distribute the terms inside the parentheses: \(3x^3 - 6x - 2x + 6x^2\)
Step 2 :Combine like terms: \(3x^3 + 6x^2 - 8x\)
Step 3 :Factor out the common factor of x: \(x(3x^2 + 6x - 8)\)
Step 4 :Final Answer: \(\boxed{x(3x^2 + 6x - 8)}\)
