Question

Create your own polynomial with a degree of 3 that when divided by x+2 has a remainder of -4.

Answer 1

This is madness bears cant do math!

Answer 2

use remainder thm .... f(c) = remainder when divided by (x-c)
so find a cubic function such that
f(-2) = -4

f(x) = (x-a)(x-b)(x-c)
try to get numbers a,b,c

Answer 3

i made one, can you tell me if it's correct

Answer 4

(6x^4-4x^3+5x^2-48x-16) / (x+2)

Answer 5

woah, its lot simpler just to leave it in factored form
also that is a 4th degree ....not a cubic

Answer 6

ohh okay

Answer 7

another tip:

f(-2) = (-2-a)(-2-b)(-2-c) = -4

make the factors: 1,1,-4 since 1*1*-4 = -4
-2-a = 1
-2-b = 1
-2-c = -4
