#

That makes so much sense! Thanks

#

Cause I thought you would plug it in seperately but you would have to simplify first the expansion of both brackets and then plug it in

#

you can do that way but there is a lot of margin for error

Oh that’s probably the reason why I got an error on my calulcsgion
