IGCSE Maths 0580 | Expanding the Brackets Explained Step by Step | From Zero to A★ with Mai Lin

Описание: Welcome back to Mai Lin’s IGCSE Mathematics Fast-Track Series!
In this lesson, we focus on a fundamental algebra skill in IGCSE Mathematics 0580 — expanding the brackets.

Expanding brackets is one of the most tested algebra techniques and appears frequently in Paper 1 and Paper 2.
If this skill is weak, solving equations, factorising expressions, and working with quadratics will become much harder.

This video explains expanding brackets clearly and logically, helping you avoid common mistakes and build strong algebra foundations.

📘 What You’ll Learn:

What it means to expand a bracket

Expanding a single bracket (e.g.
𝑎
(
𝑏
+
𝑐
)
a(b+c))

Expanding two brackets (e.g.
(
𝑎
+
𝑏
)
(
𝑐
+
𝑑
)
(a+b)(c+d))

Expanding brackets involving negative numbers

Expanding brackets with variables and coefficients

Common IGCSE exam traps when expanding

Step-by-step methods suitable for Paper 1 & Paper 2

How expanding links directly to factorising and solving equations

💡 Mai Lin’s Tip:
“Multiply everything inside the bracket.”
Take your time, stay organised, and check your signs carefully — especially negatives.

⚡ Why This Matters:
Expanding brackets is a core algebra skill that supports:

Solving linear equations

Factorising expressions

Quadratic equations

Algebraic manipulation

Mastering this topic helps you reduce careless errors and gain confidence in more advanced algebra topics.
