How to find the critical point of f(x) using Mathcad

[klian]

Suppose f(x) is the following function, defined when x>0.

f(x)=e^x - 3x - x^2

Use Mathcad to find the x-coordinate, to 2 decimal places, of the critical point f(x).

Question: How to input this function into Mathcad to get the x values? Any takers to help, I am new to Mathcad.

e^x-2*x-3=0, solve,x - Wolfram|Alpha
