Answer:   3p² + q² - 5pq - 10 < 0

Step-by-step explanation:

p² - q² + 2pq < -2p² - 2q² + 7pq + 10

since you didn't specify what to solve for, move everything from the right side to the left side of the inequality symbol using inverse operations.

(p² + 2p²) + (- q² + 2q²) + (2pq - 7pq) + (- 10) < 0

    3p²      +        q²        +      -5pq       +   -10  < 0

3p² + q² - 5pq - 10  < 0
