Question

Add these polynomials and simplify. Enter your response in standers form (x^4-9+5x^7) + ( 5x -10 +3x^4 - 2x^2)

Answer 1

5x^7+4x^4-2x^2+5x-19

Explanation:

(x^4-9+5x^7)+(5x-10+3x^4-2x^2)

x^4+3x^4+5x^7-2x^2+5x-9-10

5x^7+4x^4-2x^2+5x-19

Answer 2

5x^7 + 4x^4 - 2x^2 + 5x - 19

Explanation:

Start by copying 5x -10 +3x^4 - 2x^2 here. Next, add x^4 to +3x^4, -9 to -10, and 5x^7:

5x - 10 +3x^4 - 2x^2

- 9 +x^4 + 5x^7

-----------------------------------------

5x - 19 + 4x^4 - 2x^2 + 5x^7

Now rearrange these terms in descending order by powers of x:

5x^7 + 4x^4 - 2x^2 + 5x - 19 (answer)
