Solution for 1d/2d+3/8=-2d equation:


d in (-oo:+oo)

((1*d)/2)*d+3/8 = -2*d // + -2*d

((1*d)/2)*d-(-2*d)+3/8 = 0

(d/2)*d+2*d+3/8 = 0

1/2*d^2+2*d+3/8 = 0

DELTA = 2^2-(3/8*1/2*4)

DELTA = 13/4

DELTA > 0

d = ((13/4)^(1/2)-2)/(1/2*2) or d = (-(13/4)^(1/2)-2)/(1/2*2)

d = (13/4)^(1/2)-2 or d = -((13/4)^(1/2)+2)

d in { -((13/4)^(1/2)+2), (13/4)^(1/2)-2 }
