Answer:

Step-by-step explanation:
We want to simplify:

We first simplify the numerator to obtain:

Next the quotient rule:

We apply this quotient rule to get:

Simplify exponents:

Therefore the given expresion simplifies to:

Correct!
When thinking of what determines a plane we can make the following comparison.
If a plane was the top part of a table, 3 legs, whose tops are points W, X and Y may hold it, as shown in the first picture.
but if the legs are in a line, as in the second figure, they may not hold the top part, so 3 collinear points cannot determine a plane.
X^2 + 4x + 4
(x + 2)(x + 2) or (x + 2)^2
