Differences of Squares - Step by step :)

What is the formula for the difference of two squares?

• a^2 - b^2 = (a + b)(a - b)

• a^2 + b^2 = (a + b)(a - b)

• a^2 - b^2 = (a - b)^2

• a^2 + b^2 = (a - b)(a + b)

What does expanding (p + 5q)(p - 5q) demonstrate?

• It simplifies to p^2 + 25q^2

• It shows the formula is incorrect as terms do not cancel.

• It verifies the factorization by showing the middle terms cancel out.

• None of the above
