Hello @pompom123 and Welcome to OpenStudy! :)
this is using the distributive property
a (b + c) = (a)*(b) + (a)*(c)

The distributive property of multiplication over addition:
\(a(b + c) = ab + ac\)
Example: \(-2(3 + 4) = (-2) \cdot 3 + (-2) \cdot 4\)

OpenStudy (sleepyhead314):
hi? yes :)
I think mathstudent55 was explaining it rather well :)
if you'd like more
I was saying
the distributive property
a (b + c) = (a)*(b) + (a)*(c)
so you want to look for the option that is like
something times something plus another something times something :)
does that make more sense?
OpenStudy (sleepyhead314):
take a guess and tell me what you think it is @pompom123 :)
