Question

(3n³ - 5n + n²) - (-8n² + 3n³) please shawty please

Answer 1

`9n^2 - 5n`

Explanation:

`(3n^3 - 5n + n^2) - (-8n^2 + 3n^3)`

Lets open the brackets. Signs of all the terms in the bracket next to the minus sign will change.

`=> 3n^3 - 5n + n^2 + 8n^2 - 3n^3`

Now lets add/substract all the like terms with each other.

`=> 3n^3 - 3n^3 + n^2 + 8n^2 - 5n`

`=> 9n^2 - 5n \: \: or \:\: n(9n - 5)`

Answer 2

Explanation:

`3n^3-5n+n^2+8n^2-3n^3\\ \\ 9n^2-5n\\ \\ or\ n(9n-5)`
