Using the quadradic formula to solve x^2=5-x, what are the values of x

For this case we must solve the following equation:

By manipulating algebraically we have:

The quadratic formula is given by:

We have to:

Substituting we have:

So, we have two roots:

(- 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 )
