Factor X 2 2x 1
Factor w x 2 + 2x 1? 3
I don't know if this is possible or not, but how do you get x 2 + 2x 1?
... x 2 + 2x1
The element that completes the square
... x 2 + 2x = 1
Or x 2 + 2 (x) (1) = 1
Or x 2 + 2 (x) (1) + 1 2 = 1 2 + 1
Or (x + 1) 2 = 2
Or x + 1 = ± ˆš2
Or x + 1 ± Â ± 2 = 0
... x 2 + 2x1
= (x + 1 ˆš2) (x + 1 + ˆš2)
X 2 is 2x 1 factored.

Factor w x 2 + 2x 1?

Use the square formula to solve.
 ax² + bx + c = 0
Or
  a = 1
B = 2
   c = 1
x = [b ±  ° (b²4ac)] / (2a)
 = [2, ˆš ˆš (2Â, ² 4Â,  · 1Â,  · (1))] / (2Â, · 1)
 = [2 ±  ° 8] / 2
 = [2, ± 2à ˆš2] / 2
  = 1 ± š2
x² + 2x 1 = (x + 1à ˆš2) (x + 1 + ˆš2)
(2 + square 8) / 2 = (1 + 2 * square 2) / 2
,, x = 1/2 + square 2 or x = 1/2 square 2
