## Algebra 1: Common Core (15th Edition)

1. Remove the parentheses applying the Distributive Property. 2. Write the terms in order of their degrees. 3. Add/subtract like terms. Result: $-k^{3}+12k^{2}+8k-16$
First, remove the parentheses. The first parentheses are simply removed, and the second are removed by distributing the minus among its terms: $=8k^{2}+k-1-k^{3}+4k^{2}+7k-15$ ...Write the terms in order of their degrees $=-k^{3}+8k^{2}+4k^{2}+k+7k-1-15$ ... Add/subtract like terms =$-k^{3}+12k^{2}+8k-16$
