Answer: The numbers are 10 and 12
Step-by-step explanation:
x² + (x+2)² = 244
x² + x² + 4 + 4x = 244
2x² + 4x + 4 = 244
Dividing by 2 on both the sides we get,
x² + 2x + 2 = 122
x² + 2x - 120 = 0
x² + 12x - 10x - 120 = 0
x(x +12) - 10(x + 12 ) = 0
(x-10)(x+12) = 0
x = 10 , x ≠ -12
So x = 10
And x + 2 = 12
