Question

5. Which polynomial expresses the difference of these two polynomials?
(7k^6 + 6k – 10) - ( - 3k^6 - 7k+1)​

Answer 1

Answer:

10k^6 + 13k - 11

Step-by-step explanation:

Write (7k^6 + 6k – 10) - ( - 3k^6 - 7k+1)​ in column format:

  (7k^6 + 6k – 10)

- ( - 3k^6 - 7k+1)

Distribute the - sign throughout the second expression:

​

  (7k^6 + 6k – 10)

(  3k^6 + 7k - 1)

--------------------------     Combine like terms

 10k^6 + 13k - 11       This is the correct end result after the indicated
