1. Distribute the subtraction sign across the second polynomial.
2. Group like terms by degree.
3. Combine coefficients and write in standard form.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Failing to distribute the negative to all terms of the second polynomial.
