Answer:

Step-by-step explanation:
I am assuming this problem reads 
- So let's start on the outside and work our way towards the middle
- Starting with the
, this can be simplified to
Now we have 
- Now simplifying what is inside the parenthesis we get
- Combining what we have the simplified for of the problem becomes:

P(x) = x^4 - 9x^2 - 4x + 12
P(1) = 1^4 - 9(1)^2 - 4(1) + 12 = 1 - 9 - 4 + 12 = 0
x = 1 is a root.
By dividing the polynomial by x - 1, gives other roots as 3 and -2
