OK the next step is to multiply 3r -1 by -7r
this gives us -21r^2 + 7r and we write it below -21r^2 + 25r
and subtract
This gives us 18r and we bring down the -6 to give
18r - 6
Finally we divide 18r by -3r to give -6 then add - 6 to the r^2 - 7r on the top
then multiply -3r - 1 by -6 to give 18r - 6
subtraction then leaves nothing.
so the answer is r^2 - 7r - 6

<h3>Answer: 395 birds</h3>
==============================================
Work Shown:
The formula to use is
A = P*(1+r)^x
where,
P = 12000 is the initial population
r = -0.15 represents the growth rate in decimal form; which is really a decay/decrease due to r being negative
x = 21 days have passed by (3 weeks = 3*7 = 21 days)
These values lead to...
A = P*(1+r)^x
A = 12000*(1+(-0.15))^21
A = 12000*(1-0.15)^21
A = 12000*(0.85)^21
A = 12000*0.03294560142183
A = 395.34721706196
A = 395
Using the Fundamental Counting Theorem, there are 60 different ways to order the pizza.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with 
ways to be done, each thing independent of the other, the number of ways they can be done is:
For this problem, the parameters are found as follows:
- For the sauce, there are 2 options, cheese or tomato, hence
.
- For the topping, there are 4 options, but the options may be combined, for example, Pepperoni and Sausage, hence
.
- The topping can be added to either all the pizza or only half the pizza, hence
.
Thus the number of ways is given by:
N = 2 x 15 x 2 = 60.
