Q. Simplify. Write your answer using whole numbers and variables.z2−8zz−8
Identify Expression: Identify the expression to be simplified.The expression given is z−z28−8z. We need to simplify this expression by combining like terms if possible.
Rewrite Expression: Rewrite the expression to clarify the terms.The expression can be confusing as written. To clarify, we should consider the expression as z−(z28)−8z. This shows that we have a term with z, a term with z21, and another term with z.
Combine Like Terms: Combine like terms.In the expression z−z28−8z, we can combine the terms with z, which are z and −8z.z−8z=−7zSo now the expression is −7z−z28.
Check for Simplifications: Check for any further simplifications. The terms −7z and −z28 are not like terms and cannot be combined further. Therefore, the expression is already in its simplest form.
Write Final Expression: Write the final simplified expression.The simplified expression is −7z−z28.
