Solution for -8a-40/40-3a-a^2 equation: 


a in (-oo:+oo)

-a^2-8*a-(3*a)-(40/40) = 0

-a^2-8*a-3*a-1 = 0

-a^2-11*a-1 = 0

DELTA = (-11)^2-(-1*(-1)*4)

DELTA = 117

DELTA > 0

a = (117^(1/2)+11)/(-1*2) or a = (11-117^(1/2))/(-1*2)

a = (3*13^(1/2)+11)/(-2) or a = (11-3*13^(1/2))/(-2)

a in { (3*13^(1/2)+11)/(-2), (11-3*13^(1/2))/(-2) }
