Hi there! The numbers can be either -15 or 3.
Let the number be represented by X.
![(x + 6) {}^{2} = 81](https://tex.z-dn.net/?f=%28x%20%2B%206%29%20%7B%7D%5E%7B2%7D%20%3D%2081)
First we work out the parentheses.
![{x}^{2} + 12x + 36 = 81](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%2B%2012x%20%2B%2036%20%3D%2081)
Now subtract 81 from both sides.
![{x}^{2} + 12x - 45 = 0](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%2B%2012x%20-%2045%20%3D%200)
Using the sum of 12 and a product of 45 we get.
![(x + 15)(x - 3) = 0](https://tex.z-dn.net/?f=%28x%20%2B%2015%29%28x%20-%203%29%20%3D%200)
AB = 0 gives A = 0 or B = 0
![x + 15 = 0 \: \: or \: \: x - 3 = 0](https://tex.z-dn.net/?f=x%20%2B%2015%20%3D%200%20%5C%3A%20%5C%3A%20or%20%5C%3A%20%5C%3A%20x%20-%203%20%3D%200)
![x = - 15 \: \: or \: \: x = 3](https://tex.z-dn.net/?f=x%20%3D%20-%2015%20%5C%3A%20%5C%3A%20or%20%5C%3A%20%5C%3A%20x%20%3D%203)
Therefore, the numbers are either -15 or 3.

Answer:
18 and 3
Step-by-step explanation:
If the lowest common multiple is 18, that means both numbers must be factors of 18, so each number could be 1,2,3,3,6,9 or 18.
If the greatest common factor is 6, that means both numbers must be divisible by 6, so each number could be 6,12,18,24,30 etc.
The only numbers found in both of these sets are 6 and 18, so there is your answer.
Hope this helps.
