Let x represent the number.
.. x^2 +x = 2
.. x^2 +x +1/4 = 9/4 . . . . add 1/4 to complete the square
.. x +1/2 = ±3/2 . . . . . . . .square root
.. x = -2, 1
Numbers meeting that requirement are -2 and 1.

487/100×10^12
487×10^-2×10^12
487×10^10
The first one is already from smallest to greatest because
2/5 = 0.4 , 7/7 = 1 , and 10/9 = 1.111
The second one is already in order too because 1/10 = 0.1 , 1/3 = 0.333 , and 1/2 = 0.5
