Expanding brackets (distribution) is a fundamental algebraic skill used across many topics. Students multiply each term inside the bracket by the term outside, progressing to double-bracket expansion and expressions raised to powers.
Our tutors see these errors again and again. Knowing them in advance gives you a head start.
Forgetting to multiply the second term in the bracket (only multiplying the first)
Writing (x + 3) squared as x squared + 9 instead of x squared + 6x + 9
Sign errors when expanding brackets with negative terms
This topic is tested by the following exam boards. Our tutors are specialists in each one.
Factorising is the reverse of expanding brackets and is essential for solving quadratics, simplifying expressions, and working with algebraic fractions. Students progress from single-bracket factorisation to double brackets and the difference of two squares.
AlgebraLinear equations are one of the most frequently tested algebra topics at GCSE level. Students must isolate the unknown variable by applying inverse operations, handling brackets and fractions along the way.
AlgebraQuadratic equations appear throughout the higher tier GCSE paper and are a significant step up from linear equations. Students need to factorise, complete the square, and use the quadratic formula to find solutions.
