Question

Can someone explain how to expand algebraic equations?

Answer 1

Usually using the FOIL rule or the more general rule of multiplying everything in the first parenthesis by everything in the second parenthesis. Here are a couple examples.
(a + b)(c + d) = ac + ad +bc + bd
(a + b)(c + d + e) = ac + ad + ae + bc + bd + be

Answer 2

Thank you, however, what occurs when equations like these with intergers are given:
[-(2x-1)=\]

Answer 3

double space after each term and operation?

Answer 4

Single space.

Answer 5

Do you take issue with that? Make your point.
