There are two critical points, at

#### Explanation:

Since the derivative is already given, all we must do is solve the equation

#e^x(x^2 + 2x) = 0#

**Step 1: solving #e^x = 0#**

This has no solution, because if you take the natural logarithm of both sides, you get

#ln(e^x) = ln0#

And

**Step 2: solving #x^2 + 2x = 0#**

We have:

#x(x + 2) = 0#

#x = 0 or -2#

These are our two critical numbers.

Hopefully this helps!
