Product of 6a² – 7b + 5ab and 2ab is

The multiplication is follows:

⇒ (6a² – 7b + 5ab) × 2ab

=(6a²× 2ab – 7b× 2ab + 5ab× 2ab)

=(12a³b – 14ab² + 10 a²b²)

⇒ Result is as follows: (12a³b – 14ab² + 10 a²b²)

Option (a) does not match to our solution.

Option (b) does match to our solution.

Option (c) does not match to our solution.

Option (d) does not match to our solution.
