**[SOLVED] how do you find derivative equations?**

I'm not sure if this is the right sub forum.

## Homework Statement

f(x) = x^3 +6X^2 + 9x + 4

## Homework Equations

## The Attempt at a Solution

in my book, the first derrivative equation is 3x^2 + 12x + 9

and second equation as 6x + 12

how do you get to these equations?

I know how to calculate the difference... I'm guessing somehow that's how you get it.

I'm not even sure if my question makes sense. I'm working ahead of class, so there's a lot of gaps I need to fill in.
