Question

subract
\[(7+t-5t ^{2}+2t ^{8})-(1+2t-4t ^{2}+5t ^{8})\]

Answer 1

7-1+t-2t-5t^2+4t^2+2t^8-5t^8

Answer 2

can you do the rest by yourself?

Answer 3

i dont even know how to do these

Answer 4

i missed this lesson and i never caught up

Answer 5

I group like terms and apply "-" to the 2nd ()

what do you mean

Answer 7

I took 7 and subtract 1,
then took t and subtract 2t and so on

Answer 8

so what the next step that i have to do

Answer 9

just have to do like terms and that's it.
7-1=6
t-2t=-t and do the last two like terms

Answer 10

5t^2-4t^2=it^2
and 2t^8-5t^8=-3t^7

Answer 11

so how would i write out the solving answer

Answer 12

almost good
-5t^2+4t^2=-t^2
2t^8-5t^8=-3t^8

Answer 13

6-t-t^2-3t^8

Answer 14

that would be how i write the answer
thanks you for the help
