Completing the square is your method here:
(x^2 + 2x + 1) - 3 = 1 (I added a 1 on both sides so we can make that term squared
(x+1)^2 = 1 + 3
(x+1)^2 = 4

Answer:
 the g's contributing term for the overall uncertainty of P is  ![dP_g =  [\frac{dg}{g}]](https://tex.z-dn.net/?f=dP_g%20%3D%20%20%5B%5Cfrac%7Bdg%7D%7Bg%7D%5D)
Step-by-step explanation:
From the question we are told that 
    The pressure is   
 The first step in determining the uncertainty of P in by obtaining the terms in the equation contributing to it uncertainty and to do that we take the Ln of both sides of the equation 
     
=>    
 
Then the next step is to differentiate both sides of the equation 
     
=>    
We asked to obtain the contribution of the term g to the uncertainty of P 
This can deduced from the above equation as 
      ![dP_g =  [\frac{dg}{g}] P](https://tex.z-dn.net/?f=dP_g%20%3D%20%20%5B%5Cfrac%7Bdg%7D%7Bg%7D%5D%20P)
