algebraic expressions portfolio

3 answers

Here are a few examples of algebraic expressions that can be included in an algebraic expressions portfolio:

1. x + 5: This expression represents an unknown variable, x, added to 5. It could represent various situations, such as adding a certain quantity to an initial value.

2. 3x - 7: This expression involves an unknown variable, x, multiplied by 3 and then subtracting 7 from it. It could represent situations like scaling up or down a given value, followed by subtracting a fixed amount.

3. (2x + 4) / 3: This expression includes an unknown variable, x, being multiplied by 2 and then adding 4 to it. The resulting value is then divided by 3. It could represent situations like calculating the average or finding a ratio.

4. 2(x + 3y) - 5z: This expression involves multiple variables and operations. It includes an unknown variable, x, added to three times an unknown variable, y, and then multiplied by 2. From the resulting value, 5 times an unknown variable, z, is subtracted. It could represent scenarios where multiple variables are interacting with each other in a calculation.

5. 3(x^2) - 2xy + 4y^2: This expression includes variables raised to powers. It involves an unknown variable, x, squared, multiplied by 3. Additionally, it includes two unknown variables, x and y, being multiplied and subtracted by 2 times the product. Lastly, the expression includes an unknown variable, y, squared and multiplied by 4. It could represent situations involving quadratic equations or geometric patterns.

When creating your algebraic expressions portfolio, you can include explanations, examples, and applications of each expression. Additionally, you can include diagrams, graphs, or tables to illustrate real-life scenarios where these expressions are applicable.
