Solution for w^2-8w+12/20-5w^2 equation: 


w in (-oo:+oo)

w^2-(5*w^2)-(8*w)+12/20 = 0

w^2-5*w^2-8*w+12/20 = 0

3/5-4*w^2-8*w = 0

DELTA = (-8)^2-(-4*3/5*4)

DELTA = 368/5

DELTA > 0

w = ((368/5)^(1/2)+8)/(-4*2) or w = (8-(368/5)^(1/2))/(-4*2)

w = ((368/5)^(1/2)+8)/(-8) or w = (8-(368/5)^(1/2))/(-8)

w in { ((368/5)^(1/2)+8)/(-8), (8-(368/5)^(1/2))/(-8) }
