Question

The trinomial x2 – 3x – 4 is represented by the model.

Answer 1

Answer:

(x - 4)(x + 1)

Step-by-step explanation:

Given

x² - 3x - 4

To factor the trinomial

Consider the factors of the constant term (- 4) which sum to give the coefficient of the x- term (- 3)

The factors are - 4 and + 1, since

- 4 × 1 = - 4 and - 4 + 1 = - 3, hence

x² - 3x - 4 = (x - 4)(x + 1)
