4d)
(x - 3)² + (x + 1)² = (x - 2)² + (x + 3)²
{(x - 3) × (x - 3)} + {(x + 1) × (x + 1)} = {(x - 2) × (x - 2)} + {(x + 3) × (x + 3)}
{x² - 3x - 3x + 9} + {x² + x + x + 1} = {x² - 2x - 2x + 4} + {x² + 3x + 3x + 9}
(x² - 6x + 9) + (x² + 2x + 1) = (x² - 4x + 4) + (x² + 6x + 9)
x² + x² - 6x + 2x + 9 + 1 = x² + x² - 4x + 6x + 4 + 9
2x² - 4x + 10 = 2x² + 2x + 13
2x² - 4x + 10 - (2x² + 2x + 13) = 0
2x² - 4x + 10 - 2x² - 2x - 13 = 0
2x² - 2x² - 4x - 2x + 10 - 13 = 0
-6x - 3 = 0
6x = -3
x = -3 ÷ 6
x =
