Answer 1

Find: (6m5 + 3 – m3 – 4m) – (–m5 + 2m3 – 4m + 6)

Write subtraction of a polynomial expression as addition of the additive inverse.

(6m5 + 3 – m3 – 4m) + (m5 – 2m3 + 4m – 6)

Rewrite terms that are subtracted as addition of the opposite.

6m5 + 3 + (–m3) + (–4m) + m5 + (–2m3) + 4m + (–6)

Group like terms.

[6m5 + m5] + [3 + (–6)] + [(–m3) + (–2m3)] + [(–4m) + 4m]

Combine like terms.

Write the resulting polynomial in standard form.

m5 –

m3 +

m – 3

Answer 2

The answer would be 'All of the above' considering you see the same thing pretty much everywhere .
