Solution for (3x+9)/(2(x^2)-x-8) equation: 


D( x )

2*x^2-x-8 = 0

2*x^2-x-8 = 0

2*x^2-x-8 = 0

2*x^2-x-8 = 0

DELTA = (-1)^2-(-8*2*4)

DELTA = 65

DELTA > 0

x = (65^(1/2)+1)/(2*2) or x = (1-65^(1/2))/(2*2)

x = (65^(1/2)+1)/4 or x = (1-65^(1/2))/4

x in (-oo:(1-65^(1/2))/4) U ((1-65^(1/2))/4:(65^(1/2)+1)/4) U ((65^(1/2)+1)/4:+oo)

(3*x+9)/(2*x^2-x-8) = 0

2*x^2-x-8 = 0

2*x^2-x-8 = 0

DELTA = (-1)^2-(-8*2*4)

DELTA = 65

DELTA > 0

x = (65^(1/2)+1)/(2*2) or x = (1-65^(1/2))/(2*2)

x = (65^(1/2)+1)/4 or x = (1-65^(1/2))/4

(x-((1-65^(1/2))/4))*(x-((65^(1/2)+1)/4)) = 0

(3*x+9)/((x-((1-65^(1/2))/4))*(x-((65^(1/2)+1)/4))) = 0

3*x+9 = 0 // - 9

3*x = -9 // : 3

x = -9/3

x = -3

x = -3
