Ответ:

Таких уравнений 2:

  • (x-3)²+(y-2)²=8
  • (x-3)²+(y-6)²=8

Объяснение:

{(1 - a)}^{2} + {(4 - b)}^{2}  = 8 \ (5 - a)^{2}  +  {(4 - b)}^{2}  = 8

Вычитание из 1ой строки 2ой:

 {(1 - a)}^{2} - {(5 - a)}^{2}  = 0 \ (1 - a - 5 + a)(1 - a + 5 - a) = 0 \  - 4( - 2a + 6) = 0 \ 8(a - 3) = 0 \ a - 3 = 0 \ a = 3

Найдем b:

 {(4 - b)}^{2} - 4 = 0 \ (4 - b - 2)(4 - b + 2) = 0 \ (2 - b)(6 - b) = 0 \  =  > b = 2 \ b = 6

Таких уравнений 2:

 {(x - 3)}^{2}  +  {(y- 2)}^{2}  = 8

и

 {(x - 3)}^{2}  +  {(y - 6)}^{2}  = 8
