D( x )
x-2 = 0
x-2 = 0
x-2 = 0
x-2 = 0 // + 2
x = 2
x in (-oo:2) U (2:+oo)
(5*x^2+x-22)/(x-2) = 0
5*x^2+x-22 = 0
5*x^2+x-22 = 0
DELTA = 1^2-(-22*4*5)
DELTA = 441
DELTA > 0
x = (441^(1/2)-1)/(2*5) or x = (-441^(1/2)-1)/(2*5)
x = 2 or x = -11/5
(x+11/5)*(x-2) = 0
x+11/5 = 0
x+11/5 = 0 // - 11/5
x = -11/5
x = -11/5
