Answer:
x²-x-1
1 student = 2x + 3
x student = 2x³+x²-5x-3
CROSS MULTIPLICATION results in division of the two polynomials

Number of students in the class = (x²-x-1)
Step-by-step explanation:
Given collection from each student is (2x + 3).
Total amount collected = (2x³ + x² - 5x - 3)
Amount given by each student is a factor of the total amount collected.
So, let's assume Y is the number of students in a class,
Then Y * (2x + 3) = (2x³ + x² - 5x - 3)
= (x²-x-1)
