Question

Find the roots of (3x^3)+(6x^2)+6x+24=0

Answer 1

For some reason I can't figure this one out for the life of me.

Answer 2

Oops sorry guys it's actually a minus 24 at the end "-24"

Answer 3

can you try factor by grouping?
If we can't use factor by grouping, then we need the rational root test and factor theorem.

Answer 4

there's only one real root somewhere between 1&2

Answer 5

its not possible to factor this one out.
Best way to deal with this is to use a graphing calculator like Desmos online
