Question

Identify the polynomial written in descending order.

9 – 14x – 7x2+ x3

x3– 7x2– 14x + 9

–7x2+ 9 + x3– 14x

–14x + x3+ 9 – 7x2

Answer 1

youve got to have some idea in mind for this one ... im sure of it

Answer 2

a?

Answer 3

a is not it, but close. "a" has an "ascending" order .... so just flip out around for a descending order

Answer 4

not out :) flip IT around ...

Answer 5

Polynomial in ASCENDING order (power increases):
\[a_0+a_1x+a_2x^2+a_3x^3+...\]

Polynomial in DESCENDING order (power decreases):
\[a_nx^n+a_{n-1}x^{n-1}+a_{n-2}x^{n-2}+a_{n-3}x^{n-3}...\]

Answer 6

d

Answer 7

descending order means going down (like in descend into the cellar)
in this case, they are talking about the exponent on the x.
descending order is big to little, looking just at the exponent to figure which term goes first

Answer 8

...........

Answer 9

b?

Answer 10

In case you don't know, the exponent is the little number at the upper right of each x

Answer 11

So then it is b?

Answer 12

I hope it is clear x^3 has the biggest exponent of all the terms (3 is the biggest)
so it goes first.

Answer 13

what would be the 2nd biggest exponent ? which term ?

Answer 14

This is ASCENDING (as we move to the right, the powers go UP):
\[1+2x+6x^2+3x^3+4x^5\]
This is DESCENDING (as we go to the right, the powers go DOWN):
\[4x^5+3x^3+6x^2+2x+1\]

Answer 15

so whats the answer?
