arrange in descending order

Question

arrange in descending order

 

-4x+6x to the eighth power-2z+8x to the eighth power +4

Answer 1

Dawn, see my other answer. We can only combine terms with the same degree.

 

6x⁸ + 8x⁸ = 14x⁸

 

-4x + 8x = 4x

 

4 is by itself.

 

Our final expression is 14x⁸ + 4x + 4.

 

Hope this helps! Now onto your last question!
