Question

Can someone help me? It's urgent and thank you!

Answer 1

-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
