Answer 2

Answer:

Step-by-step explanation:

The Difference of Two Squares theorem tells us that if our quadratic equation may be written as a difference between two squares, then it may be factored into two binomials, one a sum of the square roots and the other a difference of the square roots.

This is sometimes shown by the expression A² - B² = (A + B) (A - B)

pq = A² - B²

pq = (A + B) (A - B)
