Solution for (2x^2+17x+26)/(x+6) equation: 


D( x )

x+6 = 0

x+6 = 0

x+6 = 0

x+6 = 0 // - 6

x = -6

x in (-oo:-6) U (-6:+oo)

(2*x^2+17*x+26)/(x+6) = 0

2*x^2+17*x+26 = 0

2*x^2+17*x+26 = 0

DELTA = 17^2-(2*4*26)

DELTA = 81

DELTA > 0

x = (81^(1/2)-17)/(2*2) or x = (-81^(1/2)-17)/(2*2)

x = -2 or x = -13/2

(x+13/2)*(x+2) = 0

((x+13/2)*(x+2))/(x+6) = 0

( x+13/2 )

x+13/2 = 0 // - 13/2

x = -13/2

( x+2 )

x+2 = 0 // - 2

x = -2

x in { -13/2, -2 }
