Q1 = 36 - 2P1 + P2
Q2 = 36 - 2P2 + P1
P1 and P2 = P
Q1 and Q2 = Q

Each company chooses its own price and takes the competitor's price as fixed a. Determine the profit equation and the profit value
b. Calculate the reaction curves for firm 1 and firm 2
c. Perform the Nash equilibrium determined in the competition model with differentiated products.
