Answer:
Let 1 number be x . Since the numbers are consecutive, the other number would be x + 1.
Square both and add together to equal 313.
x^2 + (x+1)^2 = 313
x^2 + x^2 + 2x + 1 = 313
2x^2 + 2x - 312 = 0
x^2 + x - 156 = 0
(x - 12)(x + 13) = 0
x = 12, x = -13
Since the number are defined to be natural, x = -13
The two numbers are 12 and -13
12^2 +(- 13)^2 = 313
