Select all of the following that are potential roots of p(x) = x4 − 9x2 − 4x + 12?

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

+/- 2,+/- 4,+/- 3,+/- 6,+/- 12

B C F G H

Step-by-step explanation:

ROOTS OF 12 -- 2, 3, 4, 6

ROOTS OF 1 -- 1

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
