Ayuda no tengo ni la menor idea de como se hace esto
x - Sqrt[x] = 156 ->
-Sqrt[x] = 156 - x ->
x = (156 - x)^2 ->
x = x^2 - 312 x + 24336 ->
-x^2 + 313 x - 24336 = 0 ->
-(x - 169) (x - 144) = 0 ->
(x - 169) (x - 144) = 0 ->
x - 169 = 0 , x - 144 = 0 ->
x = 169 , x = 144 ->
144 - Sqrt[144] = 132 <- no es 144
169 - Sqrt[169] = 156 <- si es 169
