x-3 = 0
x-3 = 0
x-3 = 0
x-3 = 0 // + 3
x = 3
x in (-oo:3) U (3:+oo)
x-(10/(x-3)) = 0
x-10*(x-3)^-1 = 0
x-10/(x-3) = 0
(x*(x-3))/(x-3)-10/(x-3) = 0
x*(x-3)-10 = 0
x^2-3*x-10 = 0
x^2-3*x-10 = 0
x^2-3*x-10 = 0
DELTA = (-3)^2-(-10*1*4)
DELTA = 49
DELTA > 0
x = (49^(1/2)+3)/(1*2) or x = (3-49^(1/2))/(1*2)
x = 5 or x = -2
(x+2)*(x-5) = 0
((x+2)*(x-5))/(x-3) = 0
((x+2)*(x-5))/(x-3) = 0 // * x-3
(x+2)*(x-5) = 0
( x+2 )
x+2 = 0 // - 2
x = -2
( x-5 )
x-5 = 0 // + 5
x = 5
