Question

we should be to taken out from p^2+q^2+2pq+10 to obtain -2p^2-2q^2+7pq+10

Answer 1

Answer:

LET THE NUMBER BE x

1. So,The equation would be p^2+q^2+2pq+10 - x = -2p^2-2q^2+7pq+10
2. p^2+q^2+2pq+10 - (-2p^2-2q^2+7pq+10) = x
3. p^2+2p^2+q^2+2q^2+2pq-7pq+10-10 = x
4. THUS,THE VALUE OF x is 3p^2+3q^2-5pq
