Question

Solve x^2 - 8x + 3 = 0 by completing the square.
Which equation is used in the process?
a. (x- 4)^2= 0
b.(x- 4)^2= 13
c. (x- 4)^2= 19

Answer 1

add to both sides 13

Answer 2

x^2 - 8x + 3 = 0
x^2-8x+16+3-16=0
x^2-8x+16-13=0
x^2-4x-4x+16=13
x(x-4)-4(x-4)=13
(x-4)(x-4)=13
(x-4)^2=13
Is that clear?
