This document provides examples for expanding brackets over single terms. It shows how to expand 2(x + 4) by distributing the 2 to both the x and 4 terms, resulting in 2x + 8. A second example expands 4(2a - 3) in the same way, distributing the 4 to both the 2a and -3 terms, giving the expression 8a - 12. The key step shown is using distribution to expand brackets over single terms inside the bracket.
