i am having a minor difficulty

i've been stuck for over an hour and don't know what to do

i don't know is this right

? = "+" or "-"

# = number

y=3

(x-3)^2 + (y-4)^2 = 9

i substitute y

(x-3)^2 + (3-4)^2 = 9

(x-3)^2 + 1 = 9

x^2 - 6x + 9 + 1 = 9

x^2 - 6x + 10 = 9

x^2 - 6x + 1 = 0

(x ? #)(x ? #) = 0

i get to here and now i am stuck

can u correct me if i did something wrong

please and thank you
