Solution for (x-4)/4=(x-3)/x equation:


D( x )

x = 0

x = 0

x = 0

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

(x-4)/4 = (x-3)/x // - (x-3)/x

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

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

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

x*(x-4)-1*4*(x-3) = 0

x^2-8*x+12 = 0

x^2-8*x+12 = 0

x^2-8*x+12 = 0

DELTA = (-8)^2-(1*4*12)

DELTA = 16

DELTA > 0

x = (16^(1/2)+8)/(1*2) or x = (8-16^(1/2))/(1*2)

x = 6 or x = 2

(x-2)*(x-6) = 0

((x-2)*(x-6))/(4*x) = 0

((x-2)*(x-6))/(4*x) = 0 // * 4*x

(x-2)*(x-6) = 0

( x-2 )

x-2 = 0 // + 2

x = 2

( x-6 )

x-6 = 0 // + 6

x = 6

x in { 2, 6 }
