What is the formula for factoring a difference of squares?

• (a + b)(a - b)

• (a - b)(a - b)

• (a^2 - b^2)

• (a + b)(a + b)

In the example, what is the first term rewritten as?

• 5 squared

• 4 squared

• 6 squared

• 3 squared

How is the second term y^2 z^2 rewritten?

• yz squared

• y squared z

• yz quantity squared

• y squared z squared

What is the 'a' term in the example?
