This is the general rule: The number of positive roots equals the number of sign changes, or a value less than that by some multiple of 2.

Look at the leading term of the equation to determine the number of roots of a polynomial. A leading term is a term with the highest power.

Thus, when we count multiplicity, a cubic polynomial can have only three roots or one root; a quadratic polynomial can have only two roots or zero roots.
