Question 347531
Hello, 
First let's add 6 to both sides of the equal sign to be:
x^2-2x+1=6
You'll see now we can complete the square which means in simple language both factors are the same:
(x-1)(x-1)=6
Or rewritten as:
(x-1)^2= 6
Now to get rid of the 2nd power, we square root both sides and it gives us:
x-1=sq rt 6
Now we add 1 to both sides to get:
x=1+sq rt 6
x=1- sq rt 6
Make sense?
