Expansion Of Algebraic Expressions
If a, b, and c are real numbers, which of the following represents the correct expansion of {eq}(a - 2)(ab + 5)(c - b) {/eq}?
A
{eq}a^2bc - a^2b^2 - 2abc + 2ab^2 + 5ac + 5ab - 10c - 10b {/eq}
B
{eq}a^2bc - a^2b^2 - 2abc + 2ab^2 + 5ac - 5ab + 5c - 5b {/eq}
C
{eq}a^2bc + a^2b^2 - 2abc + 2ab^2 + 5ac - 5ab - 10c + 10b {/eq}
D
{eq}a^2bc - 2abc + 5ac - 10c - a^2b^2 + 2ab^2 - 5ab + 10b {/eq}
