This problem so far seems impossible, so far I have e^(3x^2) =x and I can't really move forward from there. any suggestions?

It can't be solved exactly. Use a numerical method and/or technology to get an approximate answer.
There is not going to be any "algebraic" solution to that equation. That is generally true of equations that involve x both inside and outside a transcendental function.
Right so I can have e^(3x^2)-x = 0 and guess values which get me closer to 0 till I get the accuracy desired. Thanks
