expression.
f(x) = (x+3)(
x + 3
x-3
x-1
x + 1
)
?

Answer 1

The expression to find the zeros of f(x) = x² + 2x-3 is (x-1)(x+3)

Step-by-step explanation:

The expression that can be used to find the zeros of f(x) = x² + 2x-3 is:

f(x) = (x-1)(x+3)

To find the zeros of the given quadratic function, set f(x) equal to zero and solve for x. The zeros are the values of x that make the function equal to zero.

For example, if we set f(x) = x² + 2x-3 = 0 and solve it, we would get x = 1 or x = -3 as the zeros of the function.
