When students simplify algebra expressions, they often make some common mistakes. Here are a few to keep in mind:
Not Combining Like Terms: Make sure to only combine terms that have the same variable. For example, in (2x + 3x), you can combine them to get (5x). But in (2x + 3), you must leave it like that.
Wrong Distribution: Remember to distribute correctly! For (3(a + 4)), it should be simplified to (3a + 12), not (3a + 4).
Missing Negative Signs: Watch out for negative signs! In ( -(x + 2) ), it should turn into (-x - 2), not (-x + 2).
If you avoid these mistakes, simplifying algebra can be a lot easier!
