dtrain: .19=(27x^3(x))/(2.5-2x)^2
19(2.5-2x)
2 = 27x
4 where 2.5-2x not equal to 0 ==.> x not equal to 1.25
19(6.25+4x
2-10x)= 27x
4 -27x
4+76x
2-190x+118.75=0

It is interesting that two different calculators have given 2 different answers This one gives 2 answers, web2.0 calc gives only one.
Maybe i will look at another calculator and go for 2 out of 3
