Question

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 .

Answer 1

Below.

Explanation:

1. a^2 - b^2 = (a - b)(a + b)

a^2 and b^2 are 2 perfect squares and a^2 - b^2 are their difference.

2. The order of multiplication does not matter because in algebra multiplication is commutative ( meaning any order gives the same result).
