When Year 13 students use synthetic division, they often make some common mistakes. Here are a few of the biggest ones:
Wrong Coefficient Alignment: If you don’t line up the coefficients of the polynomial correctly, you can end up making mistakes. It’s very important to include all coefficients, even if some of them are zero.
Using the Remainder Theorem Incorrectly: Some students get confused when using this theorem. Remember, the remainder from synthetic division comes from how the polynomial is evaluated at the divisor.
Missing Sign Changes: Not paying attention to signs can really change the results. Always double-check your work to make sure the signs are correct.
Too Much Trust in Mental Math: If you depend on quick math in your head and don’t write down the steps, you might make mistakes. It’s better to write everything out clearly.
To avoid these mistakes, practice is key. Working through examples step by step can help you understand the process better and reduce errors in the future.
