(2p + 3q) (2p + 3q) We have three (I guess) methods we can use. But, I'm just using Latice Method. You can use this method in multiplying any polynomials.
                            2p        + 3q
                  2p     4p²         +6pq
                  3q     6pq       +9q²

Then combine the terms.

4p² + 6pq + 6pq + 9q²
= 4p² + 12pq + 9q²
1 4 1
