Answer:
[tex]36*x^6-24*x^3[/tex]
Step-by-step explanation:
We can simplify the expressio using the product rule. The exponents will add up when multiplied with each other:
[tex]=12*x^2*(3*x^4-2*x)[/tex]
[tex]=12*3*x^(2+4)-12*2*x^(2+1)[/tex]
[tex]=36*x^(6)-24*x^(3)[/tex]
The answer is B
[tex]36*x^6-24*x^3[/tex]
