Simplify Expressions

The video tutorial introduces algebraic expressions, explaining terms, variables, coefficients, and constants. It highlights the use of algebra tiles as a visual tool to represent and simplify expressions. The tutorial demonstrates how to model expressions using tiles, identify like terms, and create zero pairs for simplification. It provides examples of simplifying both simple and complex expressions, emphasizing the visual representation of algebraic processes. The video concludes by encouraging viewers to practice these skills using algebra tiles.

What is the term used for the number in front of a variable in an algebraic expression?

• Exponent

• Coefficient

• Constant

• Variable

Which of the following is NOT a characteristic of algebra tiles?

• They are used to visualize quantities.

• They are all the same color.

• They can represent both positive and negative terms.

• They come in different shapes and sizes.

What is the process of combining tiles of the same shape and size called?

• Combining like terms

• Creating zero pairs

• Grouping terms

• Simplifying expressions

In the example provided, what is the simplified expression after removing zero pairs?

• Negative 2x squared plus 5x plus 2

• Negative x squared plus 4x plus 3

• x squared plus 2x plus 1

• 2x squared plus 3x plus 1

What is the purpose of creating zero pairs when using algebra tiles?

• To add more tiles to the expression

• To visually represent the algebraic process

• To change the color of the tiles

• To increase the complexity of the expression
