Answer: Choice A

The reason why is because x = -2 leads to the denominator x+2 being zero. It's not possible to have 0 in the denominator (aka you can't divide by zero). The answer is not choice D as other x values are excluded from the domain instead of just x = -2. Recall that negative numbers aren't allowed under the square root so the domain of choice D would be x > -2 as you'd solve x+2 > 0 for x.

Answer:

Step-by-step explanation:

The GCF (Greatest Common Factor) is a number/variable that you can take out of all of the terms in the expression.

In this case, each term in this expression has a 6, and an a, but not all have an x, so we only take out:

By taking 6a, you get:

6a( $x^2$ + x + 1)
