Question

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

Answer 1

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

$9-14x-7x^2+x^3$

In option 2, the given polynomial is

$x^3-7x^2-14x+9$

In option 3, the given polynomial is

$-7x^2+9+x^3-14x$

In option 3, the given polynomial is

$-14x+x^3+9-7x^2$

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

Therefore, the correct option is 2.

Answer 2

B, x3 - 7x2 - 14x + 9
