Avoid These Algebra 2 Pitfalls
Even strong math students make these common mistakes. Learn to recognize and avoid them!
Mistake 1: Sign Errors
Forgetting to distribute negative signs is the most common error.
Wrong: \( -(3x + 2) = -3x + 2 \)
Right: \( -(3x + 2) = -3x - 2 \)
Mistake 2: Inequality Sign Flip
When multiplying or dividing by a negative number, you must flip the inequality sign.
Mistake 3: Extraneous Solutions
Radical and rational equations can produce false solutions. Always check your answers.
Mistake 4: Wrong Quadratic Formula
Students often forget the negative sign or miscalculate the discriminant.
Mistake 5: Not Checking Answers
Always substitute your answer back into the original equation to verify.
