What is the product?
(X4)(3x3-2)(4x2 +5x)

12x⁹ + 15x⁸ - 8x⁶ - 10x⁵

Step-by-step explanation:

Solution with steps, expand to get the polynomial:

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

if x = 1, then the answer is 3.5
