Question

Select a number and name of the terms of :4x^8+5x^2+9x-7

Answer 1

We are given the following expression:

`4x^8+5x^2+9x-7​`

A term in the expression is the product between a number a variable elevated to exponents, the terms in the expression are:

`\begin{gathered} 1.(4x^8) \\ 2.(5x^2) \\ 3.\text{ (9x}) \\ 4\text{ (-7}) \end{gathered}`

Therefore, there are 4 terms. In this case, the expression is called a polynomial. A monomial is when there is only one term, a binomial when there are 2 terms, and a trinomial when there are 4 terms.
