Question

1.Multiply -5ab by 3a^(2)b^(2) and verify your answer taking a=1 and b= -2​

Answer 1

Answer:

8m − 7n + 6p2) + (−3m − 4n − p2)

=8m - 3m - 7n -4n + 6p2 - p 2=5m -11n +5p2

(2m + 4n − 3p2) + (− m − n − p2).

= 2m -m + 4n -n -3p2 -p2=m + 3n -4p2

Now, (m+ 3n - 4p2) - (5m -11n +5p2)=-4m +14n -9p2
