the one on the bottom left
Step-by-step explanation:
1. difference in algebraic expression is known SUBTRACTION
a² -b²=(a+b)(a-b)
see on "a" there is square and also on b
2. no there is no matter
now let multiply (a+b) (a-b)
a²+ab-ab-b²
a²-b²
now let multiply (a-b) (a+b)
a²+ab-ba-b²
ab and ba is same
a² -b²
8 / 4+4
8/8
=1
Pls give brainliest
I think the answer is 4 units
