x^2 - 6x= -8
x^2 - 2(3)x+8+1-1=0

x^2 - 2(3)x+9=1
(x+3)^2=1

Answer 2

here you can add (b/2)^2 to both sides

Answer 3

(x-3)^2=1

Answer 4

@matricked @minimoo ,(x-3)^2=1 ,x^2 - 2(3)x+9-1=0,then x^2-6x+8=0,so x^2-6=-8

Answer 5

guys ,the solutions of this equation are 4 and 2

Answer 6

sorry x -3
