Let's add cost to both sides to make it positive and bring everything on the right over to the left and combine like terms:

For the second one:

P(x)*T(x) =

Distribute the 3x into everything inside the parenthesis to get

For the second part of that problem, C(x)*P(x) =

Distribute the x into everything first to get:

The distribute the -4 into everything to get:

Combine the like terms and put everything together to get

1 is c

2 is a

3 is a
