Question

What are the zeroes of f(x) = x2 - x - 2?

A) x = -2, 1
B) x = 2, -1
C) x = -2, -1
D) x = 2, 1

Answer 1

Is it \[x ^{2}-x-2?\]

Because if thats what you're asking the answer is 2, -1

Answer 2

Yes it is. Thank you.

Answer 3

Yeah you just have to factor it
f(x)=(x-2)(x+1)

f(x) is 0 when x =2,-1
