Answer 2

Answer:

x² + 9x + 20 = 0

Step-by-step explanation:

Given a solution x = - a for a quadratic equation then (x + a) is a factor

Here x = - 5 and x = - 4 , then corresponding factors are

(x + 5) and (x + 4)

The quadratic equation is then the product of its factors, that is

(x + 5)(x + 4) = 0 ← expand using FOIL

x² + 9x + 20 = 0
