Simplify the difference. (–7x – 5x^4 + 5) – (–7x^4 – 5 – 9x)
sineoko [7]

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
