Answer 1

Remove the brackets, add common terms

Answer 2

I don't understand the thing in a whole

Answer 3

I've told you already remove the brackets
\[-2x^3+4x^2+6+2x^2+6x+3\]
Now add common terms

Answer 4

You'd add for example
\[2x^3+3x^3\]
\[2x+x\]
\[8+6\]
These are called adding common terms

Answer 5

Nevermind, Im still confused from it even though it seems simple.
