Solution for v+2/v-1=7/2 equation: 


D( v )

v = 0

v = 0

v = 0

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

v+2/v-1 = 7/2 // - 7/2

v+2/v-(7/2)-1 = 0

v+2/v-7/2-1 = 0

1*v^1+2*v^-1-9/2*v^0 = 0

(1*v^2-9/2*v^1+2*v^0)/(v^1) = 0 // * v^2

v^1*(1*v^2-9/2*v^1+2*v^0) = 0

v^1

v^2+(-9/2)*v+2 = 0

v^2+(-9/2)*v+2 = 0

DELTA = (-9/2)^2-(1*2*4)

DELTA = 49/4

DELTA > 0

v = ((49/4)^(1/2)-(-9/2))/(1*2) or v = (-(-9/2)-(49/4)^(1/2))/(1*2)

v = 4 or v = 1/2

v in { 1/2, 4} 

v in { 1/2, 4 }
