    you will not find it using algebra, that is for sure. there is a formula for third degree polynomials but it is long and cumbersome

    Solve the function for F(x) = 0. \[F(x)=2x^3+x-5 = 0\]

    I'd usually enter it into my graphing calculator, then use the zero function to identify the crossover point on the x axis.
