Extracted text: (a) Integrate the following function by using partial fraction method. 2x² + x – 5 dx x – 4 (b) Assume we have a free market and that goods are sold at market equilibrium. Find the consumer surplus and producer surplus of the demand function pp = 200 – 0.02x² and supply function ps = 100 + x.
