Sandra is trying to foster this natural reinforcement with positive social reinforcement, "but she does not always remember".
Answer:
- <u><em>All real numbers except c = 0 and c = 3.</em></u>
Explanation:
The equation is:

Since c - 3, c, and c(c - 3) are he denominators, none of them can be equal to zero:
- c (c - 3) ≠ 0 ⇒ c ≠ 0 and c ≠ 3.
Now you can multiply both sides of the equation by the common denominator: c (c - 3):

That means the equality is valid for all real numbers for which it is defined, which is all real numbers except c = 0 and c = 3.

Gravity and Heat
"...star formation begins when part of the interstellar medium--one of the cold, dark clouds... starts to collapse under its own weight. The cloud fragment heats up as it shrinks, and eventually its center becomes hot enough for nuclear burning to begin. At that point, the contraction stops, and a star is born."
