Question 348807
mx(ab-b) =


Just multiply every term inside the parentheses by the term outside the 


parentheses.  Doing this will clear the parentheses.


mx times ab = abmx


mx times -b = -bmx


Final answer: abmx - bmx


After looking at your question a bit more carefully, I noticed that the term 


outside the parentheses is missing the letter b.


In other words, when factoring abmx - bmx, the correct factored answer is 



bmx(a - 1).


Understand?
