Answer: roots are 2, -2, -3, and 3
Step-by-step explanation:
I'm presuming the equation is x^4-9x^2-4x+12
so first group the equation by factoring out the GCF of the first two terms and last two terms
x^2(x^2-9)-4(x-3)
x^2(x-3)(x+3)-4(x-3)
(x^2-4)(x-3^2)(x+3)
(x-2)(x+2)(x+3)(x-3)^2
So
Answer:
+/- 2,+/- 4,+/- 3,+/- 6,+/- 12
