we know that
distributive property of multiplication over addition:
now, we will verify each options
option-A:
3 × (4 + 5) = (3 × 4) + (3 × 5)
We can see that both sides match with property
so, this is TRUE
option-B:
3 × (4 + 5) = (3 + 4) × (3 + 5)
We can see that right side does not match with property
so, this is FALSE
option-C:
3 × (4 + 5) = (3 × 4) + 5
We can see that right side does not match with property
so, this is FALSE
To write the any polynomial in standard form you must first put it in terms separated only by operators, then you must order terms
descendingly according to
. In your case
will be the first term because it has highest power, followed by
and
.
The standard form of this specific polynomial is:
.
Hope this helps.
