Brianne solved a quadratic equation. Her work is shown below, with Step 2 missing.
What could Brianne have written as the result from Step 2?

Given:

The given quadratic equation is

or,

And

The roots are given:

To find the missing step.

Let us solve the equation.

or,

or, [ eliminating 16 from both the side]

or,

or,

or,

Hence,

The step 2 could be

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
