# Can You Have A Negative Exponent In A Polynomial As a general rule if.

## Can you have a negative exponent in a polynomial Polynomials negative exponents objective.

Can you have a negative exponent in a polynomial. Sometimes we may not know where the roots are but we can say how many are positive or negative. Unlike e g 2x 3 3x polynomials have no poles. Polynomials cannot contain negative exponents. It can it s just that it won t be a polynomial in general and you won t be able to reason about it using most of the tools that polynomials provide.

In mathematics a polynomial is an expression consisting of variables also called indeterminates and coefficients that involves only the operations of addition subtraction multiplication and non negative integer exponentiation of variables. Every exponent in the exponent must be a non negative integer. My question is why it cannot have a negative exponent. Just by counting how many times the sign changes.

Polynomials have roots zeros where they are equal to 0. Polynomials cannot have a variable as a demonenator because that would mean it has a negative exponent. For example if n 3 5 it is not a term in a polynomial expression. This video covers solutions to problems involving exponents negative exponents adding polynomials subtracting polynomials multiplying polynomials and po.

Negative exponents can be combined in several diļ¬erent ways. Polynomials cannot contain fractional exponents. An example of a polynomial of a single indeterminate x is x 2 4x 7 an example in three variables is x 3 2xyz 2 yz 1. First the properties of polynomials.

Polynomials have a number of nice properties in that on one hand they behave a lot like integ. Negative exponents are a form of division by a variable to make the negative exponent positive you have to divide for example x 3 is the same thing as 1 x3. The simplest answer would be appreciated. 1 because polynomials as functions have certain properties that your polynomials with division don t have and 2 because there are other terms for more generalized algebraic forms.
