Understand division by variable: step 1: Understand the division by a variable.When dividing 0 by any non-zero number or variable, the result is always 0, because 0 divided by any number is 0.
Apply division rule: step ext{2}: Apply the division rule.Zero divided by α (assuming α is not zero) is 0. This is because anything times 0 is 0, so 0 divided by any non-zero number must also be 0.
Check for division error: step 3: Check for division by zero error.Since α is not specified, we must assume it is not zero to avoid division by zero, which is undefined.
