Answer:
D. 
Step-by-step explanation:

Simply subtract the two functions from each other and simplify to get the result.
I got x=-3.
Simplify both sides of the equation, then Isolate the variable.
Hope this helps! :D
P ( x ) = x³ - 4 x² + 3 x - 12 =
= x² ( x - 4 ) +3 ( x - 4 ) = ( x - 4 ) · ( x² + 3 )
x - 4 = 0, x = 4
x² + 3 = 0, x² = - 3 ( there is no real solution )
