Question

Let f (x) = x^2 - 6x - 27

Answer 1

Answer:

x = 9

x = 3

Step-by-step explanation:

find the roots of x² - 6x - 27 = 0

by factorization (or use any of your favorite methods for solving quadratic equations):

x² - 6x - 27 = 0

(x-9)(x+3) = 0

Hence,

(x-9) = 0  --------> x = 9

or

(x+3) = 0  --------> x = -3
