Question

Add the following polynomials:

(−x^3 + 26x^2 − 7x − 13) + (6x^4 − x^3 +8x + 27)

6 x4

 −2 x3  + 26 x2  −15x + 14
−6 x4  + 26 x2  + x + 14
6 x4  +26 x2  −x − 14
6 x4  −2 x3  + 26 x2  +x + 14

Answer 1

is the answer 11?

Explanation:

Answer 2

Add: (−x^3 + 26x^2 − 7x − 13) + (6x^4 − x^3 +8x + 27)

You may find it easier to write these one above the other:

(−x^3 + 26x^2 − 7x − 13)
+ (6x^4 − x^3 +8x + 27)

6x^4 -2x^3 + 26x^2 +x + 14 (answer)

Please note: You should use " ^ " to indicate exponentation.
6x4 −2x3 + 26x2 +x + 14 NO
6x4 −2x^3 + 26x^2 +x + 14 YES
