Answer:
4
Step-by-step explanation:
n represents the number
n = -12 + n2 reorder terms
n = n2 - 12 subtract n from both sides
0 = n2 - n - 12 FOIL
0 = (n - 4)(n + 3)
(-3,4)
So the only 2 numbers that could be 12 less than its square are -3 and 4, but I am pretty sure that they want positive numbers, so I would go with 4.
