Identify the polynomial written in descending order. (1 point) 9 − 14x − 7x2+ x3 x3− 7x2− 14x + 9 −7x2+ 9 + x3− 14x −14x + x3+ 9 − 7x2

Respuesta :

B, x3 - 7x2 - 14x + 9

Answer:

Option 2.

Step-by-step explanation:

We need to find a polynomial which is written in descending order.

Polynomial written in descending order: If the terms are written in a manner such that the powers on the variables go from highest to lowest, then it is called polynomial in descending order.

In option 1, the given polynomial is

[tex]9-14x-7x^2+x^3[/tex]

In option 2, the given polynomial is

[tex]x^3-7x^2-14x+9[/tex]

In option 3, the given polynomial is

[tex]-7x^2+9+x^3-14x[/tex]

In option 3, the given polynomial is

[tex]-14x+x^3+9-7x^2[/tex]

Only in option 2, the terms are arranged in descending order of powers.

Therefore, the correct option is 2.
