, LESSON 1
Algebra basics and substitution
The idea in plain English
Algebra uses letters to represent numbers. Like terms can be collected; substitution replaces letters with given
values.
What you need to know
• Only collect terms with the same variable and power.
• Use brackets when substituting negative numbers.
• Know the difference between expression, equation, identity and formula.
WORKED EXAMPLE
Question: Evaluate 2x^2+5x-1 when x=-3.
Step 1: Substitute using brackets: 2(-3)^2+5(-3)-1.
Step 2: Square first: (-3)^2=9, so 18-15-1.
Step 3: Answer=2. The brackets stop you accidentally treating -3^2 as +9 without thinking.

YOUR TURN
1. Simplify 8a+3b-5a+7b. [1-2 marks]
2. Evaluate 3x-4 for x=-2. [2-3 marks]
3. If a=4,b=-3, find 2a+b. [3-4 marks]
LESSON 2
Expanding and factorising
The idea in plain English
Expanding removes brackets by multiplying every term. Factorising reverses this by taking out common factors
or forming brackets.
What you need to know
• Every term in a bracket must be multiplied.
• Factor out the highest common factor where possible.
• For x^2+bx+c, look for two numbers multiplying to c and adding to b.
