Combining Like Terms in Algebra

The video tutorial explains how to simplify algebraic expressions by opening brackets, identifying like terms, and combining them to derive a final simplified expression. It covers the process of changing signs when dealing with negative brackets and systematically lists terms to ensure all are accounted for before simplification.

What is the first step in simplifying an expression with brackets?

• Open the brackets

• Add all the numbers first

• Divide all terms

• Multiply all terms

When opening brackets, what should you do if there is a negative sign in front?

• Add a zero to each term

• Change all signs inside the bracket

• Keep all signs the same

• Multiply each term by two

Which of the following is a like term to 3a?

• -10b²

• 6a²

• -4a

• 17B

What is the purpose of identifying like terms in an expression?

• To multiply them together

• To simplify the expression

• To divide them

• To add new terms

Which operation is performed on like terms to simplify them?

• Addition or subtraction

• Multiplication

• Exponentiation

• Division

What is the result of combining 3a and -4a?

• 7a

• 0

• -a
