Since f x is a polynomial, you can find the same real zero, and a complex conjugate pair of zeros, using the roots command. Function to solve, specified as a handle to a scalar-valued function or the name of such a function. To include extra parameters in your function, see the example Root of Function with Extra Parameter and the section Parameterizing Functions.
