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

Answer:

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

Step-by-step 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)

Answer 2

Answer:

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

Step-by-step 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
