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
(x3)^2 + (y4)^2 = 9
i substitute y
(x3)^2 + (34)^2 = 9
(x3)^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

14,500x09=1,305.oox05=6525 the answer is $6,525.00
