I believe it is an imaginary number because imaginary numbers are square roots of negative numbers.
The solution of the equations is the coordinates of the point where the two lines intersects, so the required solution is :

Answer:
f(x) = -4x^2 +48x -129
Step-by-step explanation:
It usually works well to compute the square first. That is, simplify according to the order of operations.
f(x) = -4(x^2 -12x +36) +15
f(x) = -4x^2 +48x -144 +15
f(x) = -4x^2 +48x -129
