Answer 1

Hi there!

Answer:

`\boxed{11x^2 + x - 1}`

Explanation:

`11x^2-5+x+4`

`= 11x^2 - 5 + x + 4`

Now combine the like terms.

`= 11x^2 + -5 + x + 4`

`= (11x^2) + (x) + (-5 + 4)`

`= 11x^2 + x + -1`

Have a great day!

Answer 2

11x^2 +x -1
You start with the greater power and add the like terms -5+4= -1
