Solution for 6/v-2-7/2v+7 equation: 


D( v )

v = 0

v = 0

v = 0

v in (-oo:0) U (0:+oo)

6/v-((7/2)*v)-2+7 = 0

(-7/2)*v+6/v-2+7 = 0

6*v^-1-7/2*v^1+5*v^0 = 0

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

v^1*(5*v^1-7/2*v^2+6*v^0) = 0

v^1

(-7/2)*v^2+5*v+6 = 0

(-7/2)*v^2+5*v+6 = 0

DELTA = 5^2-(4*6*(-7/2))

DELTA = 109

DELTA > 0

v = (109^(1/2)-5)/(2*(-7/2)) or v = (-109^(1/2)-5)/(2*(-7/2))

v = (109^(1/2)-5)/(-7) or v = (109^(1/2)+5)/7

v in { (109^(1/2)-5)/(-7), (109^(1/2)+5)/7} 

v in { (109^(1/2)-5)/(-7), (109^(1/2)+5)/7 }
