Which one is false about the difference of two squares?

• We can factor because there is addition sign.

• We can factor because there is a perfect squared number (Example: x², 25, 49)

• Formula: a² - b² = (a + b) (a - b)

• We can factor because there is minus sign.

Do you think you can factor this using difference of two squares?

• Yes, because there is a subtraction sign between two squared numbers

• No, you need to add them

• Yes because everything is a squared number
