Answer 2

For this you want to distribute the negative in front of the second equation

Answer 3

second term*

Answer 4

Okay. That makes sense

Answer 5

Yeah, so
\(-(7x^5+2x^4-12+6x-5x^3+x^2)\\
=> -7x^5-2x^4+12-6x+5x^3-x^2\)
Then you can simply combine like terms

Answer 6

Ah, okay.

Answer 7

Would it be -5x^5 - 5x^4 - 7x + 20?

Answer 8

\(2x^5+x^3-3x^4-x+8\\
-7x^5-2x^4+12-6x+5x^3-x^2\)
=>
\(-5x^5-5x^4\color{red}{+6x^3-x^2}-7x+20\)
You forgot those
