Please solve whole Q.8 whose answer will be correct I will mark brainliest

Answer 1

Step-by-step explanation:

let x be subtract from p²- q² + 2pq + 10 to get

-2p²- 2q² + 7pq + 10

=> p² - q² + 2pq + 10 + x = - 2p²- 2q² + 7pq + 10

=> x = - 2p² - 2q² + 7pq + 10 - p² + q² - 2pq - 10

=> x = -3p² - q² + 5pq

therefore -3p² - q² + 5pq is to be taken away
