Which equation is used in the process?


(x - 4)^2 = 0
(x - 4)^2 = 13
(x - 4)^2 = 19

Answer 1

@xoya

Answer 2

The second option

Answer 3

x2-8x+3=0
x2-2*4*x+16-13=0
(x-4)^2=13
so, it's (b)

Answer 4

LOL yeahh i was right :D

Answer 5

thanks!

Answer 6

x^2-8x+3=0
Here we are using this formula (a-b)^2=a^2-2ab+b^2
x^2-2(x)(4)+(4)^2-13=0
(x-4)^2=0+13
(x-4)^2=13

Answer 7

Your welcome :D
