Final answer:

To find the zeros of the function f(x) = x^2 + 2x - 3, you can factor the equation and solve for x: x - 1 = 0 or x + 3 = 0. The zeros are x = 1 and x = -3.


Step-by-step explanation:

To find the zeros of the function f(x) = x^2 + 2x - 3, you need to set the function equal to zero and solve for x. So, you have the equation x^2 + 2x - 3 = 0. One way to solve this equation is by factoring. By factoring, you can rewrite the equation as (x - 1)(x + 3) = 0. Then, you can set each factor equal to zero and solve for x. So, x - 1 = 0 or x + 3 = 0.

For x - 1 = 0, you can add 1 to both sides of the equation to get x = 1. For x + 3 = 0, you can subtract 3 from both sides of the equation to get x = -3. These are the zeros of the function f(x) = x^2 + 2x - 3.
