Rewrite this polynomial in terms of its simplest factors using the appropriate method: x2 − 3x − 18.
Naddik [55]

Answer:

(x - 6)(x + 3)

Step-by-step explanation:

Consider the product of the factors of the constant term which sum to give the coefficient of the x-term

product = - 18 and sum = - 3

The factors are - 6 and + 3, hence

x² - 3x - 18 = (x - 6)(x + 3)
