Solve x2 - 8x + 3 = 0 by completing the square.

Which equation is used in the process?

(x - 4) 2 = 0

(x - 4) 2 = 13

(x - 4) 2 = 19

The correct answer for this would be the second option. The equation that is used in the process in completing the square is this: (x - 4) 2 = 13.

The solution is this:

(x-4) (x-4) = 13

x^2 - 4x - 4x + 16 = 13

x^2 - 8x + 16 = 13

x^2 - 8x = 13 - 16

x^2 - 8x = - 3

x^2 - 8x + 3 = 0

Hope this answers your question. Have a great day!
