Combining Like Terms

The video tutorial explains the concept of combining like terms in algebra. It begins by discussing the importance of simplifying expressions to make them more manageable. The instructor then provides a detailed method for identifying and combining like terms, emphasizing the need to include the sign in front of terms to avoid common mistakes. A practical example is worked through, demonstrating the process of combining terms with the same variable and simplifying the expression. The tutorial concludes with a summary of the steps and the benefits of using this organized approach.

What is the primary goal of combining like terms in an expression?

• To change the variables in the expression

• To simplify the expression and make it easier to manage

• To make the expression look more complex

• To solve the equation completely

When identifying like terms, what is crucial to include?

• The exponent of the term

• The sign in front of the term

• The variable of the term

• The coefficient of the term

What mistake do people often make when combining like terms?

• Ignoring the coefficients

• Forgetting to include the sign in front of terms

• Changing the variables

• Adding terms with different exponents

In the example given, what is the result of combining 2x squared and -5x squared?

• 7x squared

• -3x squared

• 3x squared

• -7x squared

After combining like terms, what is the simplified form of 4x - x?

• 5x

• 3x

• 2x

• x
