Example Question #1 : How To Subtract Trinomials
A hockey team has 12 forwards, 6 defensemen, and 2 goalies. When they place 3 forwards, 2 defensemen, and 1 goalie on the ice, how many of each type are on the bench, (not on the ice)? F=Forward, D = Defensemen, G= Goalie
15 F, 8 D, 3 G
9 F, 4 D, 1 G
36 F, 12 D, 2 G
6 F, 2 D, 1 G
4 F, 3 D, 2 G
9 F, 4 D, 1 G
We can represent this as a subtraction of trinomials.
(12F + 6D + 2G) – (3F + 2D + 1G) = 9F + 4D + 1G.
Example Question #2 : How To Subtract Trinomials
You go to the grocery store and pick up 
1. Represent the situation with two sets of trinomials:
Before your friends ate the fruit:
The fruit your friends ate:
2. Subtract the first trinomial from the second trinomial:
Example Question #1 : How To Subtract Trinomials
Choose the answer which best simplifies the following expression:
To solve this expression, merely remove the parentheses (bearing in mind that because the second trinomial is being subtracted, it will be negative) and combine like terms:
