Factoring the Difference of Squares Quiz

What is the result when you multiply out the expression (a + b)(a - b)?

• a^2 - 2ab + b^2

• a^2 + 2ab + b^2

• a^2 + b^2

• a^2 - b^2

In the expression 16m^2 - 49, what are the values of 'a' and 'b' when applying the difference of squares formula?

• a = 2m, b = 3.5

• a = 8m, b = 14

• a = 16m, b = 49

• a = 4m, b = 7

What is the factored form of 16m^2 - 49 using the difference of squares?

• (4m + 7)(4m - 7)

• (2m + 3.5)(2m - 3.5)

• (16m + 49)(16m - 49)

• (8m + 3.5)(8m - 3.5)
