Answer:

(y - 5)(y + 4)

Step-by-step explanation:

Given

y² - y - 20

Consider the factors of the constant term (- 20) which sum to give the coefficient of the y- term (- 1)

The factors are - 5 and + 4, since

- 5 × 4 = - 20 and - 5 + 4 = - 1, thus

y² - y - 20 = (y - 5)(y + 4) ← in factored form
