the trinomial $x^{2}-3x - 4$ is represented by the model. what are the factors of the trinomial? (x + 1) and (x - 4) (x + 4) and (x - 1) (x + 5) and (x - 4) (x + 4) and (x - 5)

the trinomial $x^{2}-3x - 4$ is represented by the model. what are the factors of the trinomial? (x + 1) and (x - 4) (x + 4) and (x - 1) (x + 5) and (x - 4) (x + 4) and (x - 5)

Answer

Explanation:

Step1: Find two numbers with product -4 and sum -3

The numbers are 1 and -4 since (1 \times (-4) = -4) and (1 + (-4) = -3).

Step2: Factor the trinomial using the numbers

((x + 1)(x - 4))

Answer:

A. (x + 1) and (x − 4)
