Question 1: Which equation shows p(x)=x^6−1 factored completely over the integers? (Hint: You will need to use more than one met
kodGreya [7K]

Answer:

Question #1:  Option C, (x - 1)(x^2 + x + 1)(x + 1)(x^2 - x + 1)

Question #2:  Option C, 8x^3−56x^2+12x−84

Step-by-step explanation:

Question #1

<u>Step 1:  Factor</u>

p(x) = x^6 - 1

<em>p(x) = (x + 1)(x - 1)(x^2 + x + 1)(x^2 - x + 1)</em>

<em />

Answer:  Option C, (x - 1)(x^2 + x + 1)(x + 1)(x^2 - x + 1)

Question #2

<u>Step 1:  Expand</u>

p(x) = 4(x - 7)(2x^2 + 3)

p(x) = (4x - 28)(2x^2 + 3)

p(x) = 8x^3 + 12x - 56x^2 - 84

<em>p(x) = 8x^3 - 56x^2 + 12x - 84</em>

<em />

Answer:  Option C, 8x^3−56x^2+12x−84
