Answer:
x = -1 and x = 1
Step-by-step explanation:
<em>Excluded values</em> are values that will make the denominator of a fraction equal to 0.
The fraction is (x+1)/(x² - 1)
x² - 1 = 0
x² = 1
x = ±1
The excluded values are x = -1 and x = 1.

<u>Quadratic Equation</u>
If the roots of a quadratic equation are known, we can form the equation as follows:
where x1 and x2 are the known roots, and a is the leading coefficient.
We are given the roots as x1=1 and x2=-6, and the leading coefficient as a=5, thus:
