Question

What are the zeroes of f(x) = x2 - 2x - 3?

x= -3,1
x= -3, -1
X= 3,1
x=3, -1

Answer 1

{-1, 3}

Explanation:

Please use " ^ " to denote exponentiation: f(x) = x^2 - 2x - 3.

To find the zeros of this quadratic, set it equal to zero first:

f(x) = x^2 - 2x - 3 = 0.

Now factor this result: (x - 3)(x + 1) = 0.

The zeros are {-1, 3}
