F(x) = 3x³ - 12x² - 15x
1) Factor Outside: 3x( x² - 4x - 5)
Factor Inside: 3x(x + 1)(x - 5)
2) Set Equal To 0:
3x = 0
x + 1 = 0
x - 5 = 0
3) Solve:
x = 0, -1, 5

Step-by-step explanation:
Assuming that the topping order is not important, you need to use the combination to solve this question. The number of toppings is 12 and then added 2, so the number will become: 12+2= 14 toppings
From 14 toppings, ian need to choose 3. The possible ways would be:
14C3= 14!/(14-3)!3!= 14*13*12/ 3*2= 364 possible ways
