Answer:

Hi there! Here is your answer!

3a²b² + 5ab - 2 is the answer.

Step-by-step explanation:

Given:

1st Term = +8a²b² + 8ab - 9

2nd Term = +5a²b² + 3ab - 7

Asked:

1st Term - 2nd Term = ?

Solution:

8a²b² + 8ab - 9 - (+5a²b² + 3ab - 7)

⇒ 8a²b² + 8ab - 9 - 5a²b² - 3ab + 7

Note: All signs change in bracket when '-' sign is before brackets.

'-' changes to '+'

'+' changes to '-'

⇒ 3a²b² + 5ab - 2

Therefore,

8a²b² + 8ab - 9 - 5a²b² - 3ab + 7 = 3a²b² + 5ab - 2
