Answer: $2x^4+2x+10$

Step-by-step explanation:

You need to remember the mulplication of signs:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-$

Knowing this, you can distributive the negative sign. Then you get:

$(-7x- 5x^4 + 5) - (-7x^4 - 5 - 9x)=-7x- 5x^4 + 5 +7x^4 + 5 + 9x$

Now you need to add the like terms. Then:

$=2x+2x^4+10$

Finally, you can order the polynomial obtained in descending order. Therefore, the answer is:

$=2x^4+2x+10$
