1. Why do you think the rule is called the difference of two squares?
2. Does it matter whether the product is (a+b) (a-b) or (a-b) (a+b)? Explain .

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

translate k to n and reflect across the line containing jk.

irrational, cannot
