Answer:

25p² + 16q²​ = 164

Step-by-step explanation:

given (5p - 4q) = 12 and pq=10

consider , 25p² + 16q²

=> 25p² + 16q² = 5²p² + 4²q²

                         = (5p)² + (4q)²

                         = (5p-4q)² + 2(pq)

                         = 12² + 2(10)

                         = 144+20

                         = 164
