Answer:
D. 12x5−24x4+36x3−48x2
Step-by-step explanation:
Product means multiplication so multiply each term by 2x^2
6x^3 * 2x^2= 12x^5 (think 6*2=12 and you have to add exponents when multiplying them so 3+2=5)
- 12x^2* 2x^2= -24x^4
18x*2x^2=36x^3
-24*2x^2=-48x^2
Add all those together to get 12x5−24x4+36x3−48x2
