Question

HELP When does expanding and simplifying a(b + c) result in a positive value for ac?

Answer 1

Answer:

When c and a are positive or both are negative

Step-by-step explanation:

negative times negative equals positive so if a was negative and c was negative -a*-c= ac

Of course positive times positive equals negative so if a and c were positive we could do

a*c= ac
