Answer 1

Hello!

Answer:

$\boxed{ \bf 3x^5~-~4x^4~-~x^2~+~5}$

__________________________________

Explanation:

(3$x^{5}$ - 2$x^{4}$ - 5) - (2$x^{4}$ + x² - 10)

Drop the brackets:

3$x^{5}$ - 2$x^{4}$ - 5 - 2$x^{4}$ - x² + 10

Combine Like Terms:

3$x^{5}$ - 2$x^{4}$ - 2$x^{4}$ - x² - 5 + 10

3$x^{5}$ - 4$x^{4}$ - x² + 5

Answer 2

Answer:

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

Step-by-step explanation:

(3x^5−2x^4−5)−(2x^4+x^2−10)

Distribute the minus sign

(3x^5−2x^4−5)−2x^4-x^2+10

Combine like terms

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