Question

Are these terms in descending order?

4x^2 + 9x - 4

Answer 1

yes

Answer 2

Thanks!

Answer 3

yes, they are ordered by the size of the exponent (little number in the upper right) on the variable.

if not listed, e.g. x , the exponent is 1
if there is no x, the exponent is 0 (because x^0 = 1)

Answer 4

Oh, ok. Thanks @phi !

Answer 5

so we could write it
\[ 4x^2 + 9x^1 - 4x^0 \]
to make it more obvious
