The Roots(f(x), x) command, where f(x) is an algebraic expression, returns as a list of values points where f(x) is zero.

The Roots(f(x), x = a..b) command, where f(x) is an algebraic expression, returns as a list of values points where f(x) is zero in the interval [a,b].

If f(x) is an equation, this routine finds the roots of the expression , in the specified interval if one is provided.

If the independent variable can be uniquely determined from the expression, the parameter x need not be included in the calling sequence.

A root (or zero) of f(x) is defined as any point at which the value of the expression f(x) is  (zero).

If the expression has an infinite number of roots, a warning message and sample roots are returned.

The opts argument can contain the following equation that sets computation options.

numeric = true or false

Whether to use numeric methods (using floating-point computations) to find the roots of the expression. If this option is set to true, the points a and b must be finite and are set to  and  if they are not provided. The default value of this option is determined by the numeric values in the expression : If any of these numeric values is a floating point number (has a decimal point), then this option defaults to to true.  Note: If the numeric option is in effect, then the command does not warn about an infinite number of roots.
