x2-8x=-6
Add ((1/2)8)2 to both sides (add 16 to both sides):
x2-8x+16=10
Factor the left side:
(x-4)2=10
Take the square root of both sides
x-4 = ±√(10)
Make two equations because of the plus or minus:
x-4 = √(10) and x-4 = -√(10)
Add four to both sides (works for both equations):
x = 4+√(10) and x = 4-√(10)
