Answer 1

Sum of (a³b+6a²b²-7ab+4) and (-7a²b²+2a³b+6ab-1)

•••••> (a³b+6a²b²-7ab+4) + (-7a²b²+2a³b+6ab-1)

•••••> a³b+6a²b²-7ab+4-7a²b²+2a³b+6ab-1

•••••> a³b+2a³b+6a²b²-7a²b²-7ab+6ab+4-1

•••••> 3a³b-a²b²-ab+3

Substraction of (-6a³b+6a²b²-ab+7) from (3a³b-a²b²-ab+3)

•••••> (3a³b-a²b²-ab+3) - (-6a³b+6a²b²-ab+7)

•••••> 3a³b-a²b²-ab+3 + 6a³b-6a²b²+ab-7

•••••> 3a³b+6a³b-a²b²-6a²b²-ab+ab+3-7

•••••> 9a³b-7a²b²-4
