Question 765338
17 +2m^2 -m + m^2 +14
3m^2 -m + 31
now use quadratic formula
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}} 
======================================================================
{{{m = (1 +- sqrt( -1^2-4*3*31 ))/(2*3) }}}
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
