Answer 1

hairynmad can you help me please?

Answer 2

You combine like terms. You have three different terms: x^2, x, and integer

Answer 3

so would the x^2 + x^2 =x^4
or would it stay x^2

Answer 4

No,

examples
2x + 3x + 5x = 10x
2x^2 + 5x^2 = 7x^2

Answer 5

oh ok so
-8x^2-x+5?

Answer 6

Your question asks for the sum, so you add both equations together.
So...

-3x^2-7x+9 -5x^2+6x-4 = ?

Answer 7

Yes, that's the correct answer.

Answer 8
