Which expression can be used to find the difference of the polynomials? (10m – 6) – (7m – 4)
Answer choices
[10m + (–7m)] + [(–6) + 4](10m + 7m) + [(–6) + (–4)][(–10m) + (–7m)] + (6 + 4)[10m + (–7m)] + [6 + (–4)]

Answered by maham237 @



(10m – 6) – (7m – 4)

= 10m - 6 - 7m + 4

= 3m - 2


So

[10m + (–7m)] + [(–6) + 4]

= 3m + (-2)

= 3m - 2 ..............matching answer.

Answer

[10m + (–7m)] + [(–6) + 4]
