5-8?

Answer 6

start with putting negitives together. it makes it easier.
(5t^7-8t^3+8t^2+4)+(8t^6+4t^3-8t)

Answer 7

basically u add the negatives?

Answer 8

right
5t^7+8t^2+4+8t^6+4t^3-16t^4

Answer 9

Then add the positives together

Answer 10

@Kaylei104 I thought you add like terms?

Answer 11

that is what i've been doing if you wait for my to give the answer you would see that

Answer 12

ohhh ok :)

Answer 13

13t^9+4+12t^9- 16t^4
4+25t^18-16t^4
4+9t^22

Answer 14

@Kaylei104 why wouldnt it be this: simplified 5t^7+8t^6-4t^3+8t^2-8t+4
because i thought if it didnt have the same ^# then you could not combine them ? how do you just add them to get 9t^22, if that rule is true? I am not trying to be rude, it just seems like you know math so I want to know :)

Answer 15

The rule that you are talking about is applied is multiplication and division not adding and subtraction.

Answer 16

@Kaylei104 but read under "Like Variables-Unlike Exponents" http://www.ehow.com/info_8621373_rules-adding-variables-exponents.html

Answer 17

\[\left(5 t^7-8 t^3+8 t^2+4\right)+\left(8t^6+4 t^3-8t\right)=5 t^7+8 t^6-4 t^3+8 t^2-8 t+4 \]
