Question

Factor by grouping.
5mn+10sn-2m-4s

Answer 1

You could group them like so -

\(\large \color{red}{(5mn-2m)}+\color{green}{(10sn-4s)}\)
Now factor them

Answer 2

5mn-2m+10ns-4s

Answer 3

that's what it would be factored

Answer 4

Try looking for things that they may have in common, for example -

\(\large (5mn-2m )\) has \(\color{red}{m} \) in common, so you could factor that

\(\large (10sn-4s) \) has a common factor of \(\color{red}{2} \) and \(\color{red}{s} \)

Do you know what I mean?

Answer 5

easier for me
