Solution for (9.9+x)/0.25x=3.6 equation: 


x in (-oo:+oo)

x*((x+9.9)/0.25) = 3.6 // - 3.6

x*((x+9.9)/0.25)-3.6 = 0

(x*(x+9.9))/0.25-3.6 = 0

(x*(x+9.9))/0.25+(-3.6*0.25)/0.25 = 0

x*(x+9.9)-3.6*0.25 = 0

x^2+9.9*x-0.9 = 0

x^2+9.9*x-0.9 = 0

x^2+9.9*x-0.9 = 0

DELTA = 9.9^2-(-0.9*1*4)

DELTA = 9.9^2+3.6

DELTA = 101.61

DELTA > 0

x = ((9.9^2+3.6)^(1/2)-9.9)/(1*2) or x = (-(9.9^2+3.6)^(1/2)-9.9)/(1*2)

x = ((9.9^2+3.6)^(1/2)-9.9)/2 or x = (-((9.9^2+3.6)^(1/2)+9.9))/2

(x+((9.9^2+3.6)^(1/2)+9.9)/2)*(x-(((9.9^2+3.6)^(1/2)-9.9)/2)) = 0

((x+((9.9^2+3.6)^(1/2)+9.9)/2)*(x-(((9.9^2+3.6)^(1/2)-9.9)/2)))/0.25 = 0

((x+((9.9^2+3.6)^(1/2)+9.9)/2)*(x-(((9.9^2+3.6)^(1/2)-9.9)/2)))/0.25 = 0 // * 0.25

(x+((9.9^2+3.6)^(1/2)+9.9)/2)*(x-(((9.9^2+3.6)^(1/2)-9.9)/2)) = 0

( x+((9.9^2+3.6)^(1/2)+9.9)/2 )

x+((9.9^2+3.6)^(1/2)+9.9)/2 = 0 // - ((9.9^2+3.6)^(1/2)+9.9)/2

x = -(((9.9^2+3.6)^(1/2)+9.9)/2)

( x-(((9.9^2+3.6)^(1/2)-9.9)/2) )

x-(((9.9^2+3.6)^(1/2)-9.9)/2) = 0 // + ((9.9^2+3.6)^(1/2)-9.9)/2

x = ((9.9^2+3.6)^(1/2)-9.9)/2

x in { -(((9.9^2+3.6)^(1/2)+9.9)/2), ((9.9^2+3.6)^(1/2)-9.9)/2 }
