You can put this solution on YOUR website!
17 +2m^2 -m + m^2 +14
3m^2 -m + 31
now use quadratic formula
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
======================================================================
m+=+%281+%2B-+sqrt%28+-1%5E2-4%2A3%2A31+%29%29%2F%282%2A3%29+
from this we can see that (b^2 - 4*a*c) < 0, that is,
(-1)^2 - 4*3*31 = -371 and
square root of -371 is undefined
