Question

Add. (−x3+26x2−7x−13)+(6x4−x3+8x+27) Express the answer in standard form. Enter your answer in the box.

Answer 1

Answer:=−x3+26x2+−7x+−13+6x4+−x3+8x+27

=(6x4)+(−x3+−x3)+(26x2)+(−7x+8x)+(−13+27)

=6x4+−2x3+26x2+x+14

Answer: =6x4−2x3+26x2+x+14

Answer 2

`6x^4-2x^3+26x^2+x+14`

Explanation:

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

To add both parenthesis we remove the parenthesis first

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

`-x^3+26x^2-7x-13+6x^4-x^3+8x+27`

Now combine like terms

`-x^3+26x^2-7x-13+6x^4-x^3+8x+27`

`-2x^3+26x^2+x+14+6x^4`

Now write it in standard form with highest exponent first

`6x^4-2x^3+26x^2+x+14`
