Answer 3

Factorising expressions means expressing them as a product of simpler expressions. Here's how to factorise expressions:

1. Take out common factors: Look for common factors among the terms. Then, factor them out of each term.

Example: Factorise 6x + 9

Step 1: Take out 3 as a common factor from both terms.

6x + 9 = 3(2x + 3)

2. Use the distributive property: When a term in an expression has a common factor, use the distributive property to factor it out.

Example: Factorise 4x + 8y

Step 1: Take out 4 as a common factor.

4x + 8y = 4(x + 2y)

3. Grouping: When you can't find a common factor in the expression, group the terms in a way that they can be factorised.

Example: Factorise x² + 5x + 6

Step 1: Group the first two terms and the last two terms.

x² + 5x + 6 = (x² + 3x) + (2x + 6)

Step 2: Factorise each group.

x² + 3x = x(x + 3) and 2x + 6 = 2(x + 3)

Step 3: Combine the factors.

x² + 5x + 6 = (x + 3)(x + 2)

These are the most common methods to factorise expressions. However, there are more advanced methods for more complex expressions.
