Solution for b/2b-(6+6b)=-b2/7 equation: 


b in (-oo:+oo)

(b/2)*b-(6*b)-6 = ((-b)^2)/7 // - ((-b)^2)/7

(b/2)*b-(((-b)^2)/7)-(6*b)-6 = 0

(b/2)*b+(-1/7)*b^2-6*b-6 = 0

5/14*b^2-6*b-6 = 0

DELTA = (-6)^2-(-6*5/14*4)

DELTA = 312/7

DELTA > 0

b = ((312/7)^(1/2)+6)/(5/14*2) or b = (6-(312/7)^(1/2))/(5/14*2)

b = 7/5*((312/7)^(1/2)+6) or b = 7/5*(6-(312/7)^(1/2))

b in { 7/5*(6-(312/7)^(1/2)), 7/5*((312/7)^(1/2)+6) }
