Write \(10x^7 – 9x^2 + 15x^3 + 9\) in standard form.

A. \(10x^7 – 9x^2 + 15x^3 + 9\)

B. \(10x^7 + 15x^3 – 9x^2 + 9\)

C. \(9 + 15x^3 – 9x^2 + 10x^7\)

D. \(9 – 9x^2 + 15x^3 + 10x^7\)

Answer :

I think the answer is B

Answer:

Option B.

Step-by-step explanation:

The given polynomial is

[tex]10x^7-9x^2+15x^3+9[/tex]

In standard form of a polynomial, the terms are arranged according to its degree from left to right. It means term with highest degree should be on the left side.

Degree of [tex]10x^7,-9x^2,15x^3\text{ and }9[/tex] are 7, 2, 3 and 0.

Arrange the terms according to its degree.

[tex]10x^7+15x^3-9x^2+9[/tex]

Hence, the correct option is B.
