Add the following polynomials:(−x^3 + 26x^2 − 7x − 13) + (6x^4 − x^3 +8x + 27)6x4 −2x3 + 26x2 −15x + 14−6x4 + 26x2 + x + 146x4 +26x2 −x − 146x4 −2x3 + 26x2 +x + 14

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)
