x-24 = 25/x // - 25/x
x-(25/x)-24 = 0
x-25*x^-1-24 = 0
1*x^1-25*x^-1-24*x^0 = 0
(1*x^2-24*x^1-25*x^0)/(x^1) = 0 // * x^2
x^1*(1*x^2-24*x^1-25*x^0) = 0
x^1
x^2-24*x-25 = 0
x^2-24*x-25 = 0
DELTA = (-24)^2-(-25*1*4)
DELTA = 676
DELTA > 0
x = (676^(1/2)+24)/(1*2) or x = (24-676^(1/2))/(1*2)
x = 25 or x = -1
