72 cookies per 36 minutes = 72/36
If both values are divided by 36:
2/1, or 2 cookies per (one) minute.

Answer:
![x = 2 \: or \: x = - 2 \: or \: x = - \frac{1}{2}](https://tex.z-dn.net/?f=x%20%3D%202%20%5C%3A%20or%20%5C%3A%20x%20%3D%20%20-%202%20%5C%3A%20or%20%5C%3A%20x%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20)
Step-by-step explanation:
The given polynomial equation is
![2 {x}^{3} + {x}^{2} - 8x - 4 = 0](https://tex.z-dn.net/?f=2%20%7Bx%7D%5E%7B3%7D%20%20%2B%20%20%7Bx%7D%5E%7B2%7D%20%20-%208x%20-%204%20%3D%200)
We perform the synthetic division as shown in the attachment by dividing by x-2.
This gives a remainder of 0 and a quotient of
![2 {x}^{2} + 5x + 2](https://tex.z-dn.net/?f=2%20%7Bx%7D%5E%7B2%7D%20%20%2B%205x%20%2B%202)
This means the polynomial equation becomes:
![(x - 2)(2 {x}^{2} + 5x + 2) = 0](https://tex.z-dn.net/?f=%28x%20-%202%29%282%20%7Bx%7D%5E%7B2%7D%20%20%2B%205x%20%2B%202%29%20%3D%200)
We factor the quadratic term by splitting the middle term;
![(x - 2)(2 {x}^{2} + 4x +x + 2) = 0](https://tex.z-dn.net/?f=%28x%20-%202%29%282%20%7Bx%7D%5E%7B2%7D%20%20%2B%204x%20%2Bx%20%2B%20%202%29%20%3D%200)
![(x - 2)(2 x(x+ 2) +1(x + 2) )= 0](https://tex.z-dn.net/?f=%28x%20-%202%29%282%20x%28x%2B%202%29%20%2B1%28x%20%2B%20%202%29%20%29%3D%200)
Collect common factors again:
![(x - 2)((x+ 2)(2x + 1) = 0](https://tex.z-dn.net/?f=%28x%20-%202%29%28%28x%2B%202%29%282x%20%2B%20%201%29%20%3D%200)
The solution is:
![x = 2 \: or \: x = - 2 \: or \: x = - \frac{1}{2}](https://tex.z-dn.net/?f=x%20%3D%202%20%5C%3A%20or%20%5C%3A%20x%20%3D%20%20-%202%20%5C%3A%20or%20%5C%3A%20x%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20)
0.41567 is:
... rational because it can be expressed as a fraction (e.g., 41567/100000)
... not irrational for the same reason
... not whole (obviously)
... not integer (obviously)
