Solution for m^2-9m+4/2-m equation: 


m in (-oo:+oo)

m^2-(9*m)-m+4/2 = 0

m^2-9*m-m+4/2 = 0

m^2-10*m+2 = 0

DELTA = (-10)^2-(1*2*4)

DELTA = 92

DELTA > 0

m = (92^(1/2)+10)/(1*2) or m = (10-92^(1/2))/(1*2)

m = (2*23^(1/2)+10)/2 or m = (10-2*23^(1/2))/2

m in { (10-2*23^(1/2))/2, (2*23^(1/2)+10)/2 }
