Question

factor this polynomial completely.
5mo - mp + 10no - 2np

Answer 1

Factor it by grouping

Answer 2

Hint: Each term has two variables and there are 4 variables in all, so there will be 2 factors, each of the form (a +- b), so it will resemble (a +- b)(c +- d).

Answer 3

Another hint: arrange the variables first, then do the sign, and then do the numerical part last.
