i need on the following
convert the product into a polynomial:

c.(–2ax^2+3ax–a^2)(–a^2x^2)

d. (6.3x^3y–3y^2–0.7x)·10x^2y^2

note: the symbols such as ^ means exponents for the number to the right of it

c.

d.

Step-by-step explanation:

For this exercise you need to remember the following:

 1. The multiplication of signs:

2. The Product of powers property, which states that:

3. The Distributive property:

Knowing that, you can solve the multiplication of the polynomials:

c.

d.

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
