Question

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

Answer 1

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:

$5h^3- h - 3$
