Answer 1

just want to make sure I did it right

Answer 2

-2x^5 - x^4 - 2x^2 +8

Answer 3

:)

Answer 4

Uhm nope

Answer 5

alright well where did i go wrong

Answer 6

i did the x^5 values first then x^4 so forth blah blah blah

Answer 7

\[(3x^5 - 4x^4 + 2x^2+ 3) - (2x^5 -4x^4+3x^3 + 4x^2 -5) \]
\[\implies 3x^5 - 4x^4 + 2x^2 + 3 - 2x^5 + 4x^4 - 3x^3 -4x^2 +5 \]

Answer 8

now i have \[^{x5+{x4}-2x ^{2}+8}\]
