Answer: 6x^4 - 2x^3 + 26x^2 + x + 14.
Explanation:
Let's add the two polynomials:
(-x^3 + 26x^2 - 7x - 13) + (6x^4 - x^3 + 8x + 27)
First, let's combine like terms:
(-x^3 + 26x^2 - 7x - 13) + (6x^4 - x^3 + 8x + 27)
Rearranging similar terms:
(-x^3 - x^3) + 26x^2 - 7x + 8x - 13 + 27 + 6x^4
Simplifying the equation:
2x^3 + 26x^2 + x - 13 + 27 + 6x^4
Combining the constants:
2x^3 + 26x^2 + x + 14 + 6x^4
So, the sum of (-x^3 + 26x^2 - 7x - 13) and (6x^4 - x^3 + 8x + 27) is 6x^4 - 2x^3 + 26x^2 + x + 14.
