If the expression y2 – 16y + 64 is factored completely, which is one of its factors? (y + 8)
(y - 8)
(y - 4)
(y + 4)

b) y - 8 is one of the factor of the given expression

Step-by-step explanation:

Explanation:-

Given expression y² - 16 y + 64

                       ⇒    y² - 8 y - 8 y + 64

                       ⇒  y ( y- 8) - 8 ( y - 8)

                        ⇒ (y-8)(y-8)

Therefore  (y -8) is one of the factor
