Root( <Polynomial> )
Yields all roots of the polynomial as intersection points of the function graph and the x‐axis.
Example: Root(0.1*x^2 - 1.5*x + 5) yields A = (5, 0) and B = (10, 0).


Root( <Function>, <Initial x-Value> )
Yields one root of the function using the initial value a for a numerical iterative method.
Example: Root(0.1*x^2 - 1.5*x + 5, 6) yields A = (5, 0).


Root( <Function>, <Start x-Value>, <End x-Value> )
Let a be the Start x-Value and b the End x-Value . This command yields one root of the function in the interval [a, b] using a numerical iterative method.
Example: Root(0.1x² - 1.5x + 5, 8, 13) yields A = (10, 0).</div>


CAS Syntax

Root( <Polynomial> )
Yields all roots of the polynomial as intersection points of the function graph and the x‐axis.
Example: Root(x^3 - 3 * x^2 - 4 * x + 12) yields {x = -2, x = 2, x = 3}.
Note:
In the Menu view cas.svg CAS View, this command is only a special variant of Solve Command.
