Hi there.
Thanks for using Brainly!
First, let's rewrite to make this problem easier.
1^2 - a^2b^2
Then we must multiply the terms with equal exponents with their bases.
1^2-(ab)^2
Using the factor: a^2 - b^2=(a-b)(a+b)
We can factor using that expression.
(1-ab) x (1+ab)
After factoring, this has been our solution.
Solution: (1-ab) x (1+ab)
