Question

Identify the polynomial written in descending order.

a. 9 – 14x – 7x2+ x3
b. x3– 7x2– 14x + 9
c. –7x2+ 9 + x3– 14x
d. –14x + x3+ 9 – 7x2

Answer 1

B since when asking for descending order you look at the powers

Answer 2

Answer: Option 'b' is correct.

Explanation:

Decreasing order refers to the order that descends from highest to lowest .

But here we consider the degrees only, not the coefficient

In Option 'b' there is decreasing order of degrees,

The highest degree of that polynomial is 3 and that is written on the left most part and then descend towards the degree 0.

i.e.

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

Hence Option 'b' is correct.
