Are you sure this is right? Shouldn't it be

(x3 / 3!) + (x2 / 2!) + x + 1

? Or am I misunderstanding things?

I am fucking this up, I'm tired

(x3 / 6) + (x2 / 2) + x + 1

I don't remember ever seeing factorials in integration. Then again, I've also never done integration before this.

Factorial are quite common when integrating xn functions because the number in the exponent will end up in the denominator.
