Completing the square follows the principle of taking 

 and converting it into 

 where d is the 'correctional number' as I like to call it - i.e. the number that converts the expanded bracket into the +c, since the expanded bracket will give us 

.
In this case, 2/2=1 so we have the first part: 

.
Expanding this gives us 

. We need c to be 9, so we can just add 8.
Putting this together:

Now we can solve it more easily.
Rearranging:
 
 
        
        
        
If Jey Uso was  born on a Wednesday, the day of the week that  Roman Reigns was born is Thursday.
<h3>What day of the week was  Roman Reigns born?</h3>
There are 365 days in a year when there is no leap year. 
Now determine the number of years that make up 759 days: 759 / 365 = 2 years + 29 days
Now determine how many weeks are in 29 days : 29 / 7 = 4 weeks and 1 day 
Thus,  Roman Reigns was born on Thursday.

Step-by-step explanation:
to cancel out the bottom part of the fraction, we multiply by 3. so now we have y+1= 6. we subtract 1, and get y=5
 
        
             
        
        
        
If <em>z</em> ⁷ = 128<em>i</em>, then there are 7 complex numbers <em>z</em> that satisfy this equation.

![\implies z=\sqrt[7]{2^7} e^{i\frac17\left(\frac\pi2+2n\pi\right)}](https://tex.z-dn.net/?f=%5Cimplies%20z%3D%5Csqrt%5B7%5D%7B2%5E7%7D%20e%5E%7Bi%5Cfrac17%5Cleft%28%5Cfrac%5Cpi2%2B2n%5Cpi%5Cright%29%7D)
