X² - 15 x + 36 = 0
x² - 12x - 3x + 36 = 0
x( x - 12) - 3( x - 12) = 0
(x - 3)( x - 12) = 0
x - 3 = 0
x = 3
or
x - 12 = 0
x = 12
The solutions are 3 and 12
Answer:

Step-by-step explanation:
Given

Required
Determine the domain of the function
To do this, we need to solve for the vertex, p of the function

Given the the general form of a quadratic function is:

By comparison, we have:

So:




Substitute 1 for p in 



This implies that

The interpretation of this is that;
<em>For every value of p, there's a corresponding value of R.</em>
<em>However, because p indicates price and it's impossible to have a negative price, we can say that the minimum value of p is 0;</em>
Hence, the domain is
