Solution for (3x-4)/5+13/x=8/x+4 equation:


D( x )

x = 0

x = 0

x = 0

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

(3*x-4)/5+13/x = 8/x+4 // - 8/x+4

(3*x-4)/5+13/x-(8/x)-4 = 0

(3*x-4)/5+13/x-8*x^-1-4 = 0

(3*x-4)/5+13/x-8/x-4 = 0

(x*(3*x-4))/(5*x)+(5*13)/(5*x)+(-8*5)/(5*x)+(-4*5*x)/(5*x) = 0

x*(3*x-4)-4*5*x+5*13-8*5 = 0

3*x^2-4*x-20*x-40+65 = 0

3*x^2-4*x-20*x+25 = 0

3*x^2-24*x+25 = 0

3*x^2-24*x+25 = 0

3*x^2-24*x+25 = 0

DELTA = (-24)^2-(3*4*25)

DELTA = 276

DELTA > 0

x = (276^(1/2)+24)/(2*3) or x = (24-276^(1/2))/(2*3)

x = (2*69^(1/2)+24)/6 or x = (24-2*69^(1/2))/6

(x-((24-2*69^(1/2))/6))*(x-((2*69^(1/2)+24)/6)) = 0

((x-((24-2*69^(1/2))/6))*(x-((2*69^(1/2)+24)/6)))/(5*x) = 0

((x-((24-2*69^(1/2))/6))*(x-((2*69^(1/2)+24)/6)))/(5*x) = 0 // * 5*x

(x-((24-2*69^(1/2))/6))*(x-((2*69^(1/2)+24)/6)) = 0

( x-((2*69^(1/2)+24)/6) )

x-((2*69^(1/2)+24)/6) = 0 // + (2*69^(1/2)+24)/6

x = (2*69^(1/2)+24)/6

( x-((24-2*69^(1/2))/6) )

x-((24-2*69^(1/2))/6) = 0 // + (24-2*69^(1/2))/6

x = (24-2*69^(1/2))/6

x in { (2*69^(1/2)+24)/6, (24-2*69^(1/2))/6 }
