_______________________

When we have an equation like this, what we need to do is switch the subtraction sign into an addition sign, which then follows with combining like terms.

`(5v^3 + 4v)-(-9v - 9v^3)`

`(5v^3 + 4v)+(-9v - 9v^3)`

Distribute :

`5v^3 + 4v+9v +9v^3`

Combine like terms :

`5v^3 + 9v^3 = 14v^3`

`4v+ 9v = 13v`

`14v^3 + 13v`
