X² - 21x + 110
first you break it up into two parenthesis & since x is squared you need two x's
since 110 is positive and 21 is negitive, both of your signs need to be negitive
(x - ?)(x - ?)
then you need to think! what are the factors of 110?
Which of these factors add up to 21? those factors go in the parenthesis
Does this Help? Let me know if you need anything!
The answer to this is (x+6)(x+2)
Answer:

Step-by-step explanation:
You didn't ask any questions, but there is enough information here to determine how hotter or colder the temperature has become from in the morning till the afternoon.
Answer:
The weather is 20 7/8 degrees hotter in the afternoon than it was in the morning.
Step-by-step explanation:
Romain notices that the temperature was -11 1/2 degrees.
This corresponds to -23/2 degrees.
In the afternoon, the temperature becomes 9 3/8 degrees, which corresponds to 75/8
This statements tells us that therm temperature has been (23/2 + 75/8) degrees hotter than it was initially.
23/2 + 75/8 = 167/8 = 20 7/8
