Answer 1

`-2.4x^2-1.5x-11.4`

Explanation:

`-4.1x^2+0.9x-9.8\\\ 1.7x^2-2.4x-1.6`

Adding the polynomials.

We combine the like terms.

`(-4.1x^2+1.7x^2)+(0.9x-2.4x)+(-9.8-1.6)`

Evaluating each term separately

`-4.1x^2+1.7x^2=-2.4x^2`

`0.9x-2.4x=-1.5x`

`-9.8-1.6=-11.4` [Two negative terms when added gives the sum with a negative sign]

Combining the terms.

`(-2.4x^2)+(-1.5x)+(-11.4)`

`-2.4x^2-1.5x-11.4`
