In this lesson from the Mathsupport channel ⁨‪@mathsupportnow‬ we cover the most common mistakes students make when solving algebraic equations — from sign errors and distribution to radical misconceptions and denominator mix-ups. These are the errors that show up from Grade 9 all the way to Pre-Calculus, and this video helps you avoid them with clear examples and bonus tips.

What You’ll Learn in This Video:
✅How to apply operations to both sides of an equation
✅Why sign errors during distribution lead to incorrect solutions
✅How to correctly use the lowest common denominator in rational equations
✅Why dividing by a variable can eliminate valid solutions
✅How to expand binomials properly using FOIL
✅Common radical mistakes and how to avoid them
✅Why you can’t break up denominators or square roots
✅The difference between solving quadratic and cubic equations
✅Bonus tips on fractional expressions and equation structure
✅Final exam strategies for catching and correcting algebraic errors
