Write each polynomial in standard form. 6y5 – 4y8 – 2 + 4y3
Fed [463]

Answer:

The standard form is :

- 4 {y}^{8}  + 6 {y}^{5}  + 4 {y}^{3}  - 2

Step-by-step explanation:

A polynomial in standard form will be in decreasing powers of the variable.

The given polynomial is

6 {y}^{5}  - 4 {y}^{8}  - 2 + 4 {y}^{3}

We rearrange the terms in descending powers of y.

We start with the term with the highest degree and end with the term with the least degree.

- 4 {y}^{8}  + 6 {y}^{5}  + 4 {y}^{3}  - 2
