Common Errors to Avoid

Forgot Second Solution
high frequency

Only reporting positive solution when solving quadratics, forgetting the +/- case

Prevention tip: Always check if equation has multiple solutions

Incomplete Answer - Missing Coordinate
very high frequency

Question asks for coordinates but student only gives x-value (forgets to find y)

Prevention tip: Re-read question: does it ask for 'coordinates' or just 'x-value'?
