Solution for 150=2v+(v^2/10) equation: 


v in (-oo:+oo)

150 = (v^2)/10+2*v // - (v^2)/10+2*v

150-((v^2)/10)-(2*v) = 0

150-((v^2)/10)-2*v = 0

150-1/10*v^2-2*v = 0

DELTA = (-2)^2-(-1/10*4*150)

DELTA = 64

DELTA > 0

v = (64^(1/2)+2)/(-1/10*2) or v = (2-64^(1/2))/(-1/10*2)

v = -50 or v = 30

v in { -50, 30 }
