Solution for w^2+3w+2/5w^2-5 equation: 


w in (-oo:+oo)

w^2+(2/5)*w^2+3*w-5 = 0

7/5*w^2+3*w-5 = 0

DELTA = 3^2-(-5*7/5*4)

DELTA = 37

DELTA > 0

w = (37^(1/2)-3)/(7/5*2) or w = (-37^(1/2)-3)/(7/5*2)

w = 5/14*(37^(1/2)-3) or w = -5/14*(37^(1/2)+3)

w in { -5/14*(37^(1/2)+3), 5/14*(37^(1/2)-3) }
