## Is it possible for a polynomial to have no zeroes?

A polynomial function may have zero, one, or many zeros. All polynomial functions of positive, odd order have at least one zero, while polynomial functions of positive, even order may not have a zero. Regardless of odd or even, any polynomial of positive order can have a maximum number of zeros equal to its order.

## What are zeros in polynomials?

The zeros of a polynomial p(x) are all the x-values that make the polynomial equal to zero. They are interesting to us for many reasons, one of which is that they tell us about the x-intercepts of the polynomial’s graph. We will also see that they are directly related to the factors of the polynomial.

## Can a polynomial have more than one zero?

Multiple Zeros A polynomial can have as many zeros as its degree… For example, a polynomial with the degree 6 can have 0, 1, 2, 3, 4, 5, or 6 zeros. It is also possible for the same zero to occur more than once

## When is a polynomial p divisible by a polynomial Q?

If a polynomial P is divisible by a polynomial Q, then every zero of Q is also a zero of P. If a polynomial P is divisible by two coprime polynomials Q and R, then it is divisible by (Q • R). If P (x) = a 0 + a 1 x + a 2 x 2 + …… + a n x n is a polynomial such that deg (P) = n ≥ 0 then, P has at most “n” distinct roots.

## Which is an example of a polynomial of degree 1?

A polynomial of degree 1 is known as a linear polynomial. The standard form is ax + b, where a and b are real numbers and a≠0. 2x + 3 is a linear polynomial. A polynomial of degree 2 is known as a quadratic polynomial. x2+ 3x + 4 is an example for quadratic polynomial. Polynomial of degree 3 is known as a cubic polynomial.

## How are polynomials used in the rule of signs?

Polynomials: The Rule of Signs. A special way of telling how many positive and negative roots a polynomial has. A Polynomial looks like this: Polynomials have “roots” (zeros), where they are equal to 0: Roots are at x=2 and x=4. It has 2 roots, and both are positive (+2 and +4)
