SOLUTION: Please check my answer, I am not sure which is correct Problem: (2x^4-3x^2+8x-1)-(x^4+3x^3+x+4) answer: x^4-3x^3-3x^2+7x-5 OR x^4-3x^2+7x-5-3x^3 (x^4)+(-3x^2)+(-3x^3)+(7x

Question 737925: Please check my answer, I am not sure which is correct
Problem: (2x^4-3x^2+8x-1)-(x^4+3x^3+x+4)
answer: x^4-3x^3-3x^2+7x-5 OR x^4-3x^2+7x-5-3x^3
(x^4)+(-3x^2)+(-3x^3)+(7x)+(-5)=x^4-3x^3-3x^2+7x-5
In what order do results have to be? Which order is correct because I have been it the other way as well.
Thanks

The answers are the same, just different order.
Descending order is customary, and expected.
x^4-3x^3-3x^2+7x-5
-----------------------------
(x^4)+(-3x^2)+(-3x^3)+(7x)+(-5)=x^4-3x^3-3x^2+7x-5

-------------
Any order is correct, and they're all the same answer. Descending order makes it easier to do and to check.
