Sorry for the inconvenience caused! I mistakened (209*144)^2 as 2ab where as it is ab^2. The solution for the problem is:

209 x 144 = 30,096 with a caret symbol ^2 means to the exponent of 2 = 30096 x 30096 = 905,769,216

209 x 209 = 43,681
209 x 144 = 30,096
144 x 144 = 20,736

905,769,216 + 43,681 + 30.096 + 20,736 = 905,863,729

(a+b)^2 = a^2 + b^2 + 2ab

(209*144)^2 + (209*209)+(209*144)+(144*144) = (209+144)^2 + (209*144) = 154705

let x=209,y=144
so,equation is:
(xy)^2+(x)^2+(xy)+(y)^2
(xy)^2+(x+y)^2-xy
(x+y)^2+xy(xy-1)
putting values-
(353)^2+209*144(209*144-(1))
905863729
(209*144)^2 + (209*209)+(209*144)+(144*144) = ?
