Question

To write the polynomial 3x3 + x2 − 8x5 + 2x3 − 4x in standard form, which terms should be combined? A. 3x3 and 2x3 B. 3x3, 2x3, and x2 C. x2 and −4x D. x2 and 2x3

Answer 1

Option A. is correct

Explanation:

Like terms are those terms that have same variables of same powers. Terms that are not like terms are said to be unlike terms.

For example
`2x^3,7x^3` are like terms and
`5x^2,9x^5` are unlike terms.

Given polynomial is
`3x^3+x^2-8x^5+2x^3-4x`

Like terms need to be combined to write the polynomial in standard form

Here, like terms are
`3x^3,2x^3`

Option A. is correct.
