Adrien Luna · Answer 1

(y - 3) (y + 1)

Step-by-step explanation:

Given

(y - 1) ² - 4 ← this is a difference of squares and factors in general as

a² - b² = (a - b) (a + b), thus

(y - 1) ² - 4

= (y - 1) ² - 2²

= (y - 1 - 2) (y - 1 + 2)

= (y - 3) (y + 1) ← in factored form

Factor the following(y-1) ^2-4
