simplify: a(x+y)-a(x-y)

Answer 1

you can tkae the factor 'a' out of each term and that leaves the following:

a[(x+y)-(x-y)]
work out the value inside the square brackets first....

Answer 2

(x+y)-(x-y)

what does this work out to be?

Answer 3

ughhhh idk :( i don't understand this math

Answer 4

You never will unless you try

(x+y) - (x-y) =??

just be careful about the MINUS sign but work out that expression....

Answer 5
