Solution for a^2-8a+15/x-3 equation: 


D( x )

x = 0

x = 0

x = 0

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

a^2-(8*a)+15/x-3 = 0

a^2-8*a+15/x-3 = 0

15*x^-1 = -(a^2-8*a-3) // : 15

x^-1 = (3-a^2-(-8*a))/15

-1 < 0

1/(x^1) = (3-a^2-(-8*a))/15 // * x^1

1 = x^1*((3-a^2-(-8*a))/15) // : (3-a^2-(-8*a))/15

15*(8*a-a^2+3)^-1 = x^1

x = 15*(8*a-a^2+3)^-1

x = 15*(8*a-a^2+3)^-1
