Answer:

5h^3- h - 3

Step-by-step 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
