x² - 8x + 16 = 0

x² - 4x - 4x + 16 = 0

x(x - 4) - 4(x - 4) = 0

(x - 4)(x - 4) = 0

- - - - - - -s-

First and foremost set the equation equal to 0

x^2 - 8x + 16 = 0
Then by factoring...
(x - 4)(x - 4) = 0
Set each parenthesis equal to 0 and
x - 4 = 0
So you are forced to conclude
So x = 4

x^2-8x+16
=(x)^2-2*x*4+(4)^2
=(x-4)^2
