Factor 81-27p is

A)9(9-3p)
B)27(3-p)
C)27(54-p)
D)27(p-3)

I think A but not sure. Is there a website that explains simplifying Algebraic Expressions? Thanks for your help.

1. A is a factored result, but it isn't factored completely.
Notice that 9 - 3c still contains a common factor of 3, so you have to factor until you end up with a result that no longer contains any common factor

so,
81 - 27p
= 27(3 - p) , which is B

Notice that both A and B give you the original result.

Most textbooks label these type of questions with:
Factor fully , or, factor completely so you must arrive at a "best" answer.

2. 81 = 27 ∙ 3

81 - 27 p =

27 ∙ 3 - 27 p =

27 ( 3 - p )
