Question

completing the square
x^2-4x+1=0

Answer 1

x^2 - 4x + 4 = -1 +4
(x-2)^2 = 3
x-2 = sqrt of 3
x = (sqrt of 3) + 2

Answer 2

no, the ans should be (x - 2)^2 + 3

Answer 3

x^2 -4x+ 1 = 0
x^2 -4x = -1
x^2 - 4x + 4 = -1 +4

(x-2)^2 = 3
x-2 = +/-sqrt{3}
x = +/-sqrt{3} + 2

Answer 4

tanvidais 13, you have to solve for x when you complete the square
