Question

Arrange the following polynomial into descending order and identify the 3rd term.
18x + 2x3 − 3x2 + 10

Answer 1

Highest exponents on the left, get smaller as you go right, ending in numbers.

Answer 2

\(\bf 18x + 2x^{\color{red}{3}} - 3x^{\color{red}{ 2}} + 10\implies 18x^{\color{red}{ 1}} + 2x^{\color{red}{3}} - 3x^{\color{red}{ 2}} + 10\)

Answer 3

jdoe... isn't that ascending order?

Answer 4

ohh ahemm... well. is not.. is in no order really =)
just pointing out what the "order" means

Answer 5

True.... ascending would start that sequence with the 10 on the left :P
