Find the factored form of this trinomial.

a^2 - 2a - 24

(a - 6) (a + 4)

Step-by-step explanation:

Consider the factors of the constant term ( - 24) which sum to give the coefficient of the a - term ( - 2)

The factors are - 6 and + 4, since

- 6 * 4 = - 24 and - 6 + 4 = - 2, thus

a² - 2a - 24 = (a - 6) (a + 4) ← in factored form
