Answered by TheQuestion
Usually used with multiplication, creating an expanded algorithm is taking a formula and "drawing it out," or making it longer (and thus more simplified) by "un-distributing" it. For example:

Expand (a+b)n.

Answer: an + bn

Why: In the problem, n should be distributed to both a and b using the Distributive Property of Multiplication.

Example #2:

Expand (2+4+9)10.

Answer: 20+40+90, or 150

Why: See above.

Hope this helps!
