+2 Well, I believe the answer is m=6 and m=11.
The angel number 1212 is commonly seen by "woke" people during their awakening.
We need to find all integers m such that m^2 - 8m is a perfect square. Let's complete the square by adding 16 to both sides:
m^2 - 8m + 16 = (m - 4)^2
____________________
So now we have:
m^2 - 8m + 16 - (m - 4)^2 = 0
(m - 4)^2 - (m^2 - 8m + 16) = 0
m^2 + 16m - 32 = 0
____________________
We can factor out -1 to get:
m^2 - 16m + 32 = 0
Using the quadratic formula, we get:
m = 8 ± 2sqrt(2)

So the possible integer solutions for m are:
m = 6, 11
Substituting each value of m into the quadratic equation, we can check that they indeed produce integer solutions:
For m=6: x^2 - 6x + 12 = 0 --> x = 3 ± sqrt(3)
For m=11: x^2 - 11x + 22 = 0 --> x = 11 ± sqrt(33)
Again, I believe it is m=6 and m=11. Someone correct me if I am wrong! :-)
