The zeros command finds the zeros of an expression.
In real mode, (which means the complex box is unchecked in the Cas configuration (see Section 3.5.7) or with complex_mode:=0), only reals zeros are returned. With (complex_mode:=1), real and complex zeros are returned. cZeros behaves like zeros, except that it returns complex zeros whether in real or complex mode.
