Answer: 31?
Step-by-step explanation:
Write the coeeficientes of the polynomial in order:
| 1 - 5 6 - 30
|
|
|
------------------------
After some trials you probe with 5
| 1 - 5 6 - 30
|
|
5 | 5 0 30
-----------------------------
1 0 6 0 <---- residue
Given that the residue is 0, 5 is a root.
The quotient is x^2 + 6 = 0, which does not have a real root.
Therefore, 5 is the only root. You can prove it by solving the polynomial x^2 + 6 = 0.
Answer:
total amount of students in the class = 24
the amount of boy students in the class = 8
the amount of girl students in the class = ?

totally they are 24 students are found we know the boys then the last are girls to know how many girls are in there
24 - 8 = 16 girls.
G=16/24
