Question

A monopolist who produces 2 goods has two demand function given as Q 1 =40-2P 1 +P 2 and
Q 2 =P 1 -P 2 +15.there Q 1 and Q 2 denotes quantities of 2 goods and P 1 & P 2 prices of these goods
respectively of the cost function for the monopolist is given C=Q22+Q1Q2+Q12 then calculate
the profit maximizing quantity and price for both good. Explain how hessian Matrix will be
constructed in this case.
