Answer 1

Answer: yes

Explanation:

do u by chance still have access to those units on odyssey would love to get the answers lol.

Answer 2

p(x) = x^4 - x^3 - 9x^2 - 11x - 4

Explanation:

You are saying there are 3 roots of x = -1 and one x = 4 root

so...

p(x) = [(x + 1)^3 ] * (x - 4)

p(x) = (xxx + 3xx + 3x + 1 )*(x- 4)

p(x) = x^4 + 3 x^3 + 3x^2 + x - 4x^3 - 12xx - 12x - 4

p(x) = x^4 - x^3 - 9x^2 - 11x - 4
