Answer:

(a + 9)(a - 5)

Step-by-step explanation:

Given

a² + 4a - 45

Consider the factors of the constant term (- 45) which sum to give the coefficient of the a- term (+ 4)

The factors are + 9 and - 5 , since

9 × - 5 = - 45 and 9 - 5 = 4 , then

a² + 4a - 45 = (a + 9)(a - 5) ← in factored form
