Question

(2h3 + 6h) + (3h3 - 7h - 3) standard form sum or difference.​

Answer 1

`5h^3- h - 3`

Explanation:

Given

`(2h^3 + 6h) + (3h^3 - 7h - 3)`

Required

Standard form

We have:

`(2h^3 + 6h) + (3h^3 - 7h - 3)`

Remove bracket

`(2h^3 + 6h) + (3h^3 - 7h - 3) =2h^3 + 6h + 3h^3 - 7h - 3`

Collect like terms

`(2h^3 + 6h) + (3h^3 - 7h - 3) =2h^3 + 3h^3+ 6h - 7h - 3`

`(2h^3 + 6h) + (3h^3 - 7h - 3) = 5h^3- h - 3`

Hence, the standard form is:

`5h^3- h - 3`
