Divide the polynomial:
9x^2-21x-20 / x-1

Step-by-step explanation:

Divided using polynomial division. Hope this helps!

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
