Solution for (x^2+9x+18)/(x-2)=-0,7 equation: 


D( x )

x-2 = 0

x-2 = 0

x-2 = 0

x-2 = 0 // + 2

x = 2

x in (-oo:2) U (2:+oo)

(x^2+9*x+18)/(x-2) = -0.7 // + 0.7

(x^2+9*x+18)/(x-2)+0.7 = 0

(x^2+9*x+18)/(x-2)+(0.7*(x-2))/(x-2) = 0

0.7*(x-2)+x^2+9*x+18 = 0

x^2+9.7*x+16.6 = 0

x^2+9.7*x+16.6 = 0

x^2+9.7*x+16.6 = 0

DELTA = 9.7^2-(1*4*16.6)

DELTA = 9.7^2-66.4

DELTA = 27.69

DELTA > 0

x = ((9.7^2-66.4)^(1/2)-9.7)/(1*2) or x = (-(9.7^2-66.4)^(1/2)-9.7)/(1*2)

x = ((9.7^2-66.4)^(1/2)-9.7)/2 or x = (-((9.7^2-66.4)^(1/2)+9.7))/2

(x+((9.7^2-66.4)^(1/2)+9.7)/2)*(x-(((9.7^2-66.4)^(1/2)-9.7)/2)) = 0

((x+((9.7^2-66.4)^(1/2)+9.7)/2)*(x-(((9.7^2-66.4)^(1/2)-9.7)/2)))/(x-2) = 0

((x+((9.7^2-66.4)^(1/2)+9.7)/2)*(x-(((9.7^2-66.4)^(1/2)-9.7)/2)))/(x-2) = 0 // * x-2

(x+((9.7^2-66.4)^(1/2)+9.7)/2)*(x-(((9.7^2-66.4)^(1/2)-9.7)/2)) = 0

( x+((9.7^2-66.4)^(1/2)+9.7)/2 )

x+((9.7^2-66.4)^(1/2)+9.7)/2 = 0 // - ((9.7^2-66.4)^(1/2)+9.7)/2

x = -(((9.7^2-66.4)^(1/2)+9.7)/2)

( x-(((9.7^2-66.4)^(1/2)-9.7)/2) )

x-(((9.7^2-66.4)^(1/2)-9.7)/2) = 0 // + ((9.7^2-66.4)^(1/2)-9.7)/2

x = ((9.7^2-66.4)^(1/2)-9.7)/2

x in { -(((9.7^2-66.4)^(1/2)+9.7)/2), ((9.7^2-66.4)^(1/2)-9.7)/2 }
