The answer would be 9v ^4 + 27v ^3 - 36v^2
Step-by-step explanation:
You first would multiply each term in the parenthesis by 9v^2
9v^2 (v^2) + 9v^2 (3v) - 9v^2 (4)
After this you combine the like terms
9v^2 * v^2 is 9v^4
9v^2 * 3v is 27v^3
-9v^2 * 4 is -36v^2
Because you can not simplify it any smaller, this is your final answer
