Question

What are the zeroes of f(x) = x2 − x − 2? (1 point)

x = −2, 1

x = 2, −1

x = −2, −1

x = 2, 1

Answer 1

x² - x - 2 = 0
x² - 2x + x - 2 = 0
x(x-2) + (x-2) = 0
(x + 1)(x - 2) = 0
x + 1 = 0    or    x - 2 = 0
x = -1                x = 2

Answer: x = 2, −1

Answer 2

Answer: Use a calculator and you get 2,-1 as your answer
