/ 2 \ 2 / 2 \ 2 log(2)*\x - 5/*log (3)*(7 - x) + 3*log(2)*\x - 5/ - 2*log (3)*(7 - x) - 6 = 0
a*x^2 + b*x + c = 0
D = b^2 - 4 * a * c =
(0)^2 - 4 * (-log(2)) * (2 + 5*log(2)) = 4*(2 + 5*log(2))*log(2)
x1 = (-b + sqrt(D)) / (2*a)
x2 = (-b - sqrt(D)) / (2*a)
-3 - 7*log3^2 + x*log3^2 = 0
x = 3 / ((-7*log(3)^2 + x*log(3)^2)/x)
