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=x

(x+1)squared + (y+1)squared = 6

i substitute y

(x+1)squared + (x+1)squared = 6

x squared + 2x + 1 + x squared + 2x + 1 = 6

2x squared + 4x + 2 = 6

2x squared + 4x - 4 = 0

2(x squared + 2x - 2) = 0

2(x ? #)(x ? #)

i get to here and now i am stuck

can u correct me if i did something wrong

please and thank you
