Solution for ln(14/a*x^2*-2x)*-2 equation: 


D( x )

-2*(14/a)*x*x^2 <= 0

-2*(14/a)*x*x^2 <= 0

-2*(14/a)*x*x^2 <= 0

-2*(14/a)*x*x^2 = 0

-28*a^-1*x^3 = 0 // : -28*a^-1

x^3 = 0

x = 0

x <= 0

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


x in (0:+oo)

-2*ln(-2*(14/a)*x*x^2) = 0

-2*ln(-2*(14/a)*x*x^2) = 0 // : -2

ln(-2*(14/a)*x*x^2) = 0

ln(-2*(14/a)*x*x^2) = ln(e^0)

-2*(14/a)*x*x^2 = e^0

-2*(14/a)*x*x^2-e^0 = 0

-28*a^-1*x^3 = 1 // : -28*a^-1

x^3 = 1/(-28*a^-1)

x^3 = 1/(-28*a^-1) // ^ 1/3

x = 1/(-28^(1/3)*a^(-1/3))

x = 1/(-28^(1/3)*a^(-1/3))
