Question

What are the zeroes of f(x) = x2 − 2x − 3? (4 points)

Select one:
a. x = −3, 1
b. x = −3, −1
c. x = 3, 1
d. x = 3, −1

Answer 1

3, -1

Explanation:

We first set the equation equal to zero.

x^2 - 2x - 3

`x^(2) - 2x - 3\\x^(2) -1x - 1x -3\\(x^(2) - 1x) - (x + 3)\\x(x - 1) - 1(x + 3`

So the zeroes are -1, 3, or 3, -1

Answer 2

HI, the correct answer for the quadratic equation is d. x= 3,-1
