Question

Explain why the solution does not include x=-2.

Answer 1

see the explanation

Explanation:

we have

`(3)/(x+2)+4\geq 3`

Remember that in a quotient the denominator cannot be equal to zero

For x=-2 the denominator in the left side is equal to zero

so

In this problem the value of x cannot be equal to x=-2

Because, For x=-2 the expression in the left side is undefined
