Solution for -3/4x=-5/x equation: 


D( x )

x = 0

x = 0

x = 0

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

(-3/4)*x = -5/x // + -5/x

(-3/4)*x-(-5/x) = 0

(-3/4)*x+5*x^-1 = 0

5*x^-1-3/4*x^1 = 0

(5*x^0-3/4*x^2)/(x^1) = 0 // * x^2

x^1*(5*x^0-3/4*x^2) = 0

x^1

(-3/4)*x^2+5 = 0

(-3/4)*x^2+5 = 0

DELTA = 0^2-(4*5*(-3/4))

DELTA = 15

DELTA > 0

x = (15^(1/2)+0)/(2*(-3/4)) or x = (0-15^(1/2))/(2*(-3/4))

x = -2/3*15^(1/2) or x = 2/3*15^(1/2)

x in { -2/3*15^(1/2), 2/3*15^(1/2)} 

x in { -2/3*15^(1/2), 2/3*15^(1/2) }
