Answer:

(4pq + 3q) {}^{2}  - (4pq - 3q) {}^{2}  \\ using \: identity \\  {x}^{2}  -  {y}^{2}  = (x + y)(x - y) \\ where \\ x = 4pq + 3q\\ y = 4pq - 3q \\then \: lhs =  \\  (4pq + 3q) {}^{2}  - (4pq - 3q) {}^{2} \\  = (4pq + 3q + 4pq - 3q)(4pq + 3q - 4pq + 3q) \\  = 8pq \times 6q \\  = 48 {p}^{2} q = rhs \\ lhs = rhs

104 \times 105 \\ (100 + 4) \times (100 + 5) \\  {100}^{2}  + (4 + 5) \times 100 + (4 \times 5) \\  = 10000 + 900 + 45 = 10945
