Question

How do you factor `x^3 + 2x + 3`?

Answer 1

I would start by trying to reduce the order using Ruffini's Method:

So you get that (using the red circled first result):
`x^3+2x+3=(x+1)(x^2-x+3)`
Solving the quadratic with the Quadratic Formula you should get two Complex results.
So, I think that you have:
`x^3+2x+3=(x+1)(x^2-x+3)`
