GCSE Maths - How to Expand Single Brackets #35

The video tutorial explains how to expand single brackets in algebraic expressions. It covers three examples, demonstrating both the addition of like terms and the multiplication method for quicker solutions. The tutorial also addresses how to handle multiple terms inside brackets and separate terms outside brackets, providing a comprehensive understanding of the topic.

What is the result of adding three sets of the expression 2x + 3y?

• 10x + 15y

• 4x + 6y

• 6x + 9y

• 8x + 12y

Which method is faster for expanding a single bracket with one term outside?

• Adding terms together

• Guessing the result

• Multiplying the outside term with each inside term

• Using a calculator

What is the result of multiplying 5a by the terms 4a, -3b, and 6 inside a bracket?

• 30a^2 - 25ab + 40a

• 25a^2 - 20ab + 35a

• 15a^2 - 10ab + 25a

• 20a^2 - 15ab + 30a

In the final example, what is the simplified result of 2x + 3(x - 5)?

• 5x - 15

• 6x - 10

• 4x - 20

• 7x - 25

What is the first step in expanding the expression 3(x - 5) when 2x is separate?

• Add 2x to 3x

• Multiply 3 by x and -5

• Divide 3 by x

• Subtract 5 from x
