Question

Find the sum: (3x2 + 5x − 8) + (5x2 − 13x − 5)

Answer 1

8x^2 - 8x - 13 hope this helps

Answer 2

`(3x^2+5x-8)+(5x^2-13x-5)=8x^2-8x-13`

Explanation:

The given polynomials are,

`3x^2+5x-8,5x^2-13x-5`

In polynomial addition and subtraction only like terms can be added or subtracted.

So,

`=(3x^2+5x-8)+(5x^2-13x-5)`

`=3x^2+5x-8+5x^2-13x-5`

`=3x^2+5x^2+5x-13x-8-5`

`=8x^2-8x-13`
