    I'm not sure if there is an easier method for this question, but I have always used this method to solve quartic equations

    For the amount of effort involved in trying to solve it algebraically, I'd use a numerical technique like Newton Raphson.

    Use Excel's Solver Add-in tool.
    Enter the formula =T^4 + T into cell A1.
    The target value is 185.
    Choose any blank cell to show the result:
