5/12-(2*(12/5)^9) = (5/12)^2*x+1 // - (5/12)^2*x+1
5/12-((5/12)^2*x)-(2*(12/5)^9)-1 = 0
5/12-((5/12)^2*x)-2*(12/5)^9-1 = 0
-25/144*x-123848400323/23437500 = 0 // + 123848400323/23437500
-25/144*x = 123848400323/23437500 // : -25/144
x = 123848400323/23437500/(-25/144)
x = -1486180803876/48828125
x = -1486180803876/48828125
