Answer:
zb - zc
Explanation:
When using the distributive property, the result will be the sum of the products of the outside number with each of the inside numbers.
Here, the outside number is z and the inside terms are b and -c. So, our two products are z * b and z * (-c). Then we need to add these together: z * b + z * (-c) = zb - zc
