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:

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

The polynomials P(x)=x^3−x−2 and Q(x)=x^2+2x+1 are multiplied and the result is completely simplified.

GarryVolchara [31]

Answer:

C. 2x^4; E. -5x

Step-by-step explanation:

P(x) = x^3 − x − 2 and Q(x) = x^2 + 2x + 1

P(x) * Q(x) = (x^3 − x − 2)(x^2 + 2x + 1) =

= x^5 + 2x^4 + x^3 - x^3 - 2x^2 - x - 2x^2 - 4x - 2

= x^5 + 2x^4 - 4x^2 - 5x - 2

Answer: C. 2x^4; E. -5x
