Me with my math (image attached is the problem)!

C. p + q = b and D. p . q = c. The two  true statements about p and q for a quadratic trinomial of the form x² + bx + c that can be factored as (x + p)(x + q) is p + q = b and p . q = c.

The easiest way to solve this problem is developing the product (x + p)(x + q) to a trinomial quadratic form.

(x + p)(x + q) = x² + qx + px + p.q = x² + (p + q)x + p.q

The equation above has the form x² + bx + c from which we can deduce the coefficients of x² + (p + q)x + p.q as follow:

a = 1, b = p + q, and c = p . q

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

what is the model?
