Question

The maximum number of roots which a cubic polynomial can have

​

Answer 1

Answer:

1 or 3 roots

Step-by-step explanation:

A polynomial of degree n can have only an even number fewer than n real roots. 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. This is useful to know when factoring a polynomial.
