Question

Combine like terms. Write all answers in descending order.
12t6 − t3 + 8t6 + 4t3 − t7 − 3t3

Answer 1

12t6 − t3 + 8t6 + 4t3 − t7 − 3t3
-t7+20t6

Answer 2

\[-t^7+20t^6\]

Answer 3

I'm lost

Answer 4

write it in order of power first, then do the math on it...
\[-t^7+12t^6+8t^6-t^3-3t^3+4t^3\]
\[-t^7+20t^6+0t^3\]

Answer 5

combine the like terms means take the number letter combination and add it to the same letter number combination. so for example take t6, you have a positive 12t6 and a positive 8t6 so you can add them to create 20t6. -t3 and -3t3 create -4t3 and so forth. then after you combine all of the combinations just put them in biggest to smallest order

Answer 6

is it just this -t7 + 20t6 without the 0t3

Answer 7

yes!
