What are the zeroes of f(x) = x^2 − x − 2?
a. x = −2, 1
b. x = 2, −1
c. x = −2, −1
d. x = 2, 1

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

so, converting firstly the mixed fractions to improper fractions and then "adding".
