## When can expression be a polynomial?

For an expression to be a polynomial term, any variables in the expression must have whole-number powers (or else the “understood” power of 1, as in x1, which is normally written as x). A plain number can also be a polynomial term.

## What are polynomials used for in real life?

Polynomials are used in engineering, computer and math based jobs, in management, business and even in farming. In all careers requiring knowledge of polynomials, variables and constants are used to create expressions defining quantities which are known and unknown.

## What are polynomial functions?

A polynomial function is a function such as a quadratic, a cubic, a quartic, and so on, involving only non-negative integer powers of x. We can give a general defintion of a polynomial, and define its degree.

## What is polynomial function in your own words?

A polynomial function is a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation like the quadratic equation, cubic equation, etc. For example, 2x+5 is a polynomial that has exponent equal to 1.

## What is polynomial and its types?

Polynomials are algebraic expressions that may comprise of exponents which are added, subtracted or multiplied. Polynomials are of different types. Namely, Monomial, Binomial, and Trinomial. A monomial is a polynomial with one term. A trinomial is an algebraic expression with three, unlike terms.

## What is the types of polynomial?

Types of Polynomials

• Monomial: An algebraic expression that contains only one non-zero term is known as a monomial.
• Binomial: An algebraic expression that contains two non zero terms is known as a binomial.
• Trinomial: An algebraic expression that contains three non-zero terms is known as the Trinomial.

## What is real roots of a polynomial?

When we see a graph of a polynomial, real roots are x-intercepts of the graph of f(x). Let’s look at an example: The graph of the polynomial above intersects the x-axis at (or close to) x=-2, at (or close to) x=0 and at (or close to) x=1. The polynomial will also have linear factors (x+2), x and (x-1).
