Hel

Step-by-step explanation:

If you use long division to divide y² - 49 by y - 7, you get the other factor y + 7

                   y   +   7

  y - 7 ║    y²  -  0 y  -  49

             - (y²   -   7y)     ↓

                    + 7y  -  49

                    - (7y  -  49)

⇒  y² - 49  = (y - 7) (y + 7)

false
