GCSE Maths - How to Simplify Expressions by Collecting Like Terms #28

The video tutorial explains how to simplify algebraic expressions by combining like terms. It defines terms as collections of numbers and variables separated by addition or subtraction signs. The tutorial demonstrates how to identify like terms, which have the same combination of variables, and how to combine them by considering their signs. Several example problems are solved to illustrate the process, showing how to handle terms with different variables and coefficients.

What is a term in an algebraic expression?

• A symbol representing a number

• A collection of numbers and variables multiplied or divided together

• A single number

• A variable raised to a power

Why can't an A^2 term be combined with an A term?

• Because they have different coefficients

• Because A^2 is a different variable

• Because A^2 is a squared term and not a simple A term

• Because they are separated by a subtraction sign

How do you combine like terms in an expression?

• By multiplying them together

• By adding them together, considering the sign in front

• By dividing them by their coefficients

• By subtracting the smaller term from the larger term

In the expression 3X + 2 - 3X + 6, what is the simplified result?

• 6

• 8

• 0

• 3X + 8

What is the final simplified form of the expression 5A - 8A + 6B + 1?

• -3A + 7B + 1

• 3A + 6B + 1

• 5A + 6B + 1

• -3A + 6B + 1
