Answer 1

Answer:

y^2 - (4)^2

a^2 - b^2 = (a+b)(a-b)

using this

(y+4)(y-4)

Hope it helps.....

Answer 2

Step-by-step explanation:

$given \: polynomial \: = \: {y}^{2} - 16 \\ because \: {a}^{2} - {b}^{2} = (a + b) \: (a - b) \\ {(y)}^{2} - {(4)}^{2} = (y + 4) \: (y - 4) \\ \\ \\ hope \: it \: helps \: you \\ please \: mark \: as \: brainliest$
