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

c?

Answer 2

its not c/?

Answer 3

Maybe seeing the steps will help:
\[x^2-8x+3=0\]\[x^2-8x+4^2+3=16\]\[x^2-8x+4^2=13\]Factor that and you'll get:\[(x-4^2)=13\]
Any questions on how that was done?

Answer 4

nope. got it.

Answer 5

Answer 6
