Solution for -1/19(x^2-18x-19) equation: 


x in (-oo:+oo)

(-1/19)*(x^2-(18*x)-19) = 0

(-1/19)*(x^2-18*x-19) = 0

-1/19*(x^2-18*x-19) = 0

x^2-18*x-19 = 0

x^2-18*x-19 = 0

DELTA = (-18)^2-(-19*1*4)

DELTA = 400

DELTA > 0

x = (400^(1/2)+18)/(1*2) or x = (18-400^(1/2))/(1*2)

x = 19 or x = -1

(x+1)*(x-19) = 0

-1/19*(x+1)*(x-19) = 0

( x+1 )

x+1 = 0 // - 1

x = -1

( x-19 )

x-19 = 0 // + 19

x = 19

x in { -1, 19 }
