Answer 1

Respuesta:

c) 3

Explicación paso a paso:

(x + 3)! = (x² + 3x + 2)(x² + 3x)

               x          + 1

               x          + 2

(x + 3)! = (x + 1)(x + 2)(x² + 3x)

(x + 3)! = (x + 1)(x + 2)x(x + 3)

(x + 3)(x + 2)(x + 1)x(x - 1)! = x(x + 1)(x + 2)(x + 3)

(x - 1)! = 1

x - 1 = 0

x₁ = 1

x - 1 = 1

x = 1 + 1

x₂ = 2

x₁ + x₂ = 1 + 2

x₁ + x₂ = 3
