DELTA = (-7)^2-(1*4*10)
DELTA = 9
DELTA > 0
x = (9^(1/2)+7)/(1*2) or x = (7-9^(1/2))/(1*2)
x = 5 or x = 2
x in (-oo:2) U (2:5) U (5:+oo)
(x-5)/(x^2-(7*x)+10) = 0
(x-5)/(x^2-7*x+10) = 0
x^2-7*x+10 = 0
x^2-7*x+10 = 0
DELTA = (-7)^2-(1*4*10)
DELTA = 9
DELTA > 0
x = (9^(1/2)+7)/(1*2) or x = (7-9^(1/2))/(1*2)
x = 5 or x = 2
(x-2)*(x-5) = 0
(x-5)/((x-2)*(x-5)) = 0
x-5 = 0 // + 5
x = 5
x in { 5}
x belongs to the empty set
