Arrange in descending order.
1.) -c + 3 + 2c^2
2.) p^2 - 3p^3 + 9 - 2p^4 + 6p
3.) -3x + x^5 + 7
4.) 9a - 5 + a^3 - 2a^2
5.) 3e^2 - 2e + 5
I assume you mean arrange each polynomial in descending order of powers. Surely you can order a set of integers. For example,
#2) p^2 - 3p^3 + 9 - 2p^4 + 6p = -2p^4 - 3p^3 + p^2 + 6p + 9
do the others in like wise.
