Solution for 10x^2-(1/100)x-1=0 equation: 


x in (-oo:+oo)

10*x^2-((1/100)*x)-1 = 0

10*x^2+(-1/100)*x-1 = 0

10*x^2-1/100*x-1 = 0

DELTA = (-1/100)^2-(-1*4*10)

DELTA = 400001/10000

DELTA > 0

x = ((400001/10000)^(1/2)+1/100)/(2*10) or x = (1/100-(400001/10000)^(1/2))/(2*10)

x = ((400001/10000)^(1/2)+1/100)/20 or x = (1/100-(400001/10000)^(1/2))/20

x in { (1/100-(400001/10000)^(1/2))/20, ((400001/10000)^(1/2)+1/100)/20 }
