Step-by-step explanation:
Two problem questions for the default cases could be:
- How many floors can the elevator go up if each person gets off on a different floor?
- If two couples get off on floors 4 and 6, respectively, how many couples are left in the elevator?
<h3>How to create questions?</h3>
To create problem questions about a topic, we must take into account the data we have about that problem in order to pose a question that expands our knowledge about it or that is adapted to the information we already know.
According to the above, in the case of couples and individuals waiting in the elevator, we must create questions taking into account the hypothetical cases in which there are 3 couples and 6 separate people.
So, the questions we can create are:
- How many floors can the elevator go up if each person gets off on a different floor?
- If two couples get off at the 4th and 6th floors, respectively, how many couples are left in the elevator?

Answer:
(x - 10)(x + 10)
Step-by-step explanation:
x² - 100 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
x² - 100
= x² - 10²
= (x - 10)(x + 10)
