Answer:
Graphical method of solving polynomial equation cannot identify the imaginary roots.
Explanation:
In graphical method, we plot the graph of the polynomial whose roots are to be calculated.
And where the graph intercepts the x-axis, those points are the real roots of the corresponding polynomial.
But in case we need to find the complex or imaginary roots the graphical method fails because we can only find real roots using the graphical, method of solving polynomial equations.
Hence, Graphical method of solving polynomial equation cannot identify the imaginary roots.
