Solution for (y+1)/(y^2-3y-18)=0 equation: 


D( y )

y^2-(3*y)-18 = 0

y^2-(3*y)-18 = 0

y^2-(3*y)-18 = 0

y^2-3*y-18 = 0

y^2-3*y-18 = 0

DELTA = (-3)^2-(-18*1*4)

DELTA = 81

DELTA > 0

y = (81^(1/2)+3)/(1*2) or y = (3-81^(1/2))/(1*2)

y = 6 or y = -3

y in (-oo:-3) U (-3:6) U (6:+oo)

(y+1)/(y^2-(3*y)-18) = 0

(y+1)/(y^2-3*y-18) = 0

y^2-3*y-18 = 0

y^2-3*y-18 = 0

DELTA = (-3)^2-(-18*1*4)

DELTA = 81

DELTA > 0

y = (81^(1/2)+3)/(1*2) or y = (3-81^(1/2))/(1*2)

y = 6 or y = -3

(y+3)*(y-6) = 0

(y+1)/((y+3)*(y-6)) = 0

y+1 = 0 // - 1

y = -1

y = -1
