Rewrite this function in the form that reveals the minimum of the function.

c (p) = p^2-28p+250

Given that the function is given by:

c (p) = p^2-28p+250

The minimum value of the function is at the derivative of c' (p)

thus from the function given:

c (p) = p^2-28p+250

c' (p) = 2p-28

Thus the minimum function is c' (p) = 2p-28
