(x^2)^2+2*x^2*4+16-16-9

(x^2+4)^2-25

(x^2+4)-5^2

(x^2+4-5) (x^2+4+5)

Answer: If you are looking to factor, then the answer would be (x-1)(x^3+x^2+x+9)

Step-by-step explanation: You can use the rational root theorem which we can express (x-1)x^4+8x-9/x-1 and this can be simplified to (x-1)(x^3+x^2+x+9)
