x in (-oo:+oo)
x^2-(15*x)-(1/50) = 0
x^2-15*x-1/50 = 0
x^2-15*x-1/50 = 0
DELTA = (-15)^2-(-1/50*1*4)
DELTA = 5627/25
DELTA > 0
x = ((5627/25)^(1/2)+15)/(1*2) or x = (15-(5627/25)^(1/2))/(1*2)
x = ((5627/25)^(1/2)+15)/2 or x = (15-(5627/25)^(1/2))/2
x in { (15-(5627/25)^(1/2))/2, ((5627/25)^(1/2)+15)/2 }
