Answer:

-6 and -1

Explanation:

The excluded values are the values of x that satisfy
2x^(2) + 14x + 12 = 0

Let us solve the equation
2x^(2) + 14x + 12 = 0

It's a quadratic equation

Thus, let us calculate the discriminant Δ

Δ
= 14^(2) - 4 .2.12 = 100

the discriminant is greater than 0, so the equation has two solutions


x = (-14 - 10)/(4) = (-24)/(4) = -6 or
x = (-14+10)/(4) = (-4)/(4) = -1

the excluded values are -6 and -1
