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:

[tex]6x^4-2x^3+26x^2+x+14[/tex]

Step-by-step explanation:

[tex](-x^3+26x^2-7x-13)+(6x^4-x^3+8x+27)[/tex]

To add both parenthesis we remove the parenthesis first

[tex](-x^3+26x^2-7x-13)+(6x^4-x^3+8x+27)[/tex]

[tex]-x^3+26x^2-7x-13+6x^4-x^3+8x+27[/tex]

Now combine like terms

[tex]-x^3+26x^2-7x-13+6x^4-x^3+8x+27[/tex]

[tex]-2x^3+26x^2+x+14+6x^4[/tex]

Now write it in standard form with highest exponent first

[tex]6x^4-2x^3+26x^2+x+14[/tex]
