The answer to this problem is 45. What I did was 12x4.5
The equilibruim point of a demand and supply function is the point at which the quantity demanded is equal to the quantity supplied.
Given the demand function as
![p = -0.1x^2 - x + 33](https://tex.z-dn.net/?f=p%20%3D%20-0.1x%5E2%20-%20x%20%2B%2033)
and the supply function as
![p = 0.1x^2 + 2x + 13](https://tex.z-dn.net/?f=p%20%3D%200.1x%5E2%20%2B%202x%20%2B%2013)
The equilibruim quantity is obtained as follows:
![-0.1x^2 - x + 33=0.1x^2 + 2x + 13 \\ \\ \Rightarrow0.2x^2+3x+46=0 \\ \\ \Rightarrow x=-7.5\pm13.18i](https://tex.z-dn.net/?f=-0.1x%5E2%20-%20x%20%2B%2033%3D0.1x%5E2%20%2B%202x%20%2B%2013%20%5C%5C%20%20%5C%5C%20%5CRightarrow0.2x%5E2%2B3x%2B46%3D0%20%5C%5C%20%20%5C%5C%20%5CRightarrow%20x%3D-7.5%5Cpm13.18i)
There is no real equilibruim quantity and price for the given demand and supply function.
