Cubic binomial. There is one variable of 2 that is raised to the cubic power.
Answer:
y ≠ 9, y ≠ 3
Step-by-step explanation:
y² -12y +27 = (y - 9) (y - 3)
Denominator ≠ 0
y ≠ 9 or y ≠ 3
Well, considering this is a Math Joke, I believe, the answer is, "Because it is the scenter." Or (Center).
Hoped this helped! :)
