12-6y+y^2
well this involves imaginary numbers and if you don't know how to deal with them then there is no way to simplify this, otherwise its just the quadratic formula.
a = 1
b = -6
c = 12
y+=+%28-b+%2B-+sqrt%28b%5E2-%284%2Aa%2Ac%29%29%29%2F%282%2Aa%29
y+=+%286+%2B-+sqrt%28%28-6%29%5E2-%284%2A1%2A12%29%29%29%2F%282%29
y+=+%286+%2B-+sqrt%2836-%284%2A12%29%29%29%2F%282%29
y+=+%286+%2B-+sqrt%2836-48%29%29%2F%282%29
y+=+%286+%2B-+sqrt%28-12%29%29%2F%282%29
y+=+%286+%2B-+2%2Asqrt%283%29i%29%2F%282%29
y+=+3+%2B-+sqrt%283%29i
