Question

What should be subtracted from 4p²-2pq-6q²-r+5 to get -p²+pq-8q²-2r+6

Answer 1

Answer:

5p²-3pq+2q²+r-1

Step-by-step explanation:

To get the required equation we have to subtract the given equation with the equation -p²+pq-8q²-2r+6

4p²-2pq-6q²-r+5-(-p²+pq-8q²-2r+6)

after solving this we get ,

5p²-3pq+2q²+r-1

for check,

4p²-2pq-6q²-r+5-(5p²-3pq+2q²+r-1)

=4p²-2pq-6q²-r+5-5p²+3pq-2q²-r+1

= -p²+pq-8q²-2r+6
