Question

Find the sum of these polynomials (x^6 + x + 9) + (7x^6 + 5) =

Answer 1

8 x^6 + x + 14

Explanation:

Simplify the following:

7 x^6 + x^6 + x + 5 + 9

Grouping like terms, 7 x^6 + x^6 + x + 5 + 9 = (x^6 + 7 x^6) + x + (9 + 5):

(x^6 + 7 x^6) + x + (9 + 5)

x^6 + 7 x^6 = 8 x^6:

8 x^6 + x + (9 + 5)

9 + 5 = 14:

Answer: 8 x^6 + x + 14

Answer 2

For this case we must find the sum of the following polynomials:

`x ^ 6 + x + 9\ and\ 7x ^ 6 + 5`

We have:

`(x ^ 6 + x + 9) + (7x ^ 6 + 5) =`

We eliminate parentheses:

`x ^ 6 + x + 9 + 7x ^ 6 + 5 =`

We add similar terms:

`x ^ 6 + 7x ^ 6 + x + 9 + 5 =\\8x ^ 6 + x + 14`

Finally we have that the sum of the polynomials is:
`8x ^ 6 + x + 14`

Answer:

`8x ^ 6 + x + 14`
