Frequently Asked Questions

Simplifying algebraic expressions is a fundamental skill. It’s used extensively throughout O-Level Math and beyond, allowing you to solve equations, factorize, and manipulate formulas efficiently. Strong simplification skills are crucial for accuracy and speed in exams.
Forgetting to multiply *every* term inside the bracket by the term outside is a very common error. For example, a(b + c) = ab + ac, not just ab. Always double-check that each term has been multiplied correctly.
Pay very close attention to the signs! When expanding brackets with a negative sign in front, remember that it changes the sign of *every* term inside the bracket. For example, -(a - b) = -a + b. Consider rewriting the expression to clearly show the multiplication of -1 if needed.
The key is to find a common denominator before adding or subtracting fractions. Remember to multiply both the numerator and denominator of each fraction by the appropriate factor to achieve the common denominator.
Only combine terms that have the *exact* same variable and exponent. For example, 3x² and 5x² can be combined (8x²), but 3x² and 5x cannot. Highlighting or underlining like terms can help prevent mistakes.
Slow down and double-check each step! Its better to be accurate than fast. Also, try practicing with simpler problems to build confidence and focus on accuracy before tackling more complex ones. Consider working with a tutor to identify specific areas where you are consistently making errors.
