# Multiplying brackets

When multiplying expressions in brackets, make sure that everything inside the bracket is multiplied by the term (or number) outside the bracket.

Expand 2(3x + 4)

### Method 1 - Boxes

What is 2(3x + 4)?

### Method 2 - Lines

What is 2(3x + 4)?

Use either method, but remember that everything inside the bracket must be multiplied by the term (or number) outside the bracket.

## Bracket x bracket

What happens when we have more than a single term or number outside the bracket? What happens when we have another bracket.

For example, if we want to expand (a + b)(c + d), we need to make sure that everything in the second bracket is multiplied by everything in the first.

We can do this in two ways, using boxes or lines.

You can choose either method, boxes or lines, but make sure that you multiply everything. Remember, too, that a '+' or '-' symbol belongs to the number or term immediately after it.

### Example

Expand (x - 3)(x + 2)
