Introduction
In mathematics, equivalent expressions are expressions that have the same value, but may be written in different ways. When simplifying or rewriting expressions, it's essential to ensure that the resulting expression is equivalent to the original. In this article, we'll analyze the equivalent expression written by Tyrone and identify the error he made.
The Original Expression
The original expression is . This expression can be simplified by combining like terms.
Simplifying the Original Expression
To simplify the original expression, we need to combine the like terms. The like terms in this expression are the constants (28, 7, and 4), the x terms (x and 5x), and the n terms (2n and n).
28 + x + 2n + 7 + n + 5x + 4
= (28 + 7 + 4) + (x + 5x) + (2n + n)
= 39 + 6x + 3n
Tyrone's Equivalent Expression
Tyrone's equivalent expression is . This expression can be simplified by combining the like terms.
Simplifying Tyrone's Equivalent Expression
To simplify Tyrone's equivalent expression, we need to combine the like terms. The like terms in this expression are the constants (39), the x terms (5x and x), and the n terms (3n).
3n + 5x + 39 + x
= 3n + (5x + x) + 39
= 3n + 6x + 39
Identifying the Error
Comparing the simplified original expression with Tyrone's simplified equivalent expression, we can see that the error is in the x term. The original expression has a combined x term of 6x, while Tyrone's equivalent expression has a combined x term of 6x + x, which is equivalent to 7x.
Conclusion
In conclusion, Tyrone made an error in his equivalent expression by not combining the x terms correctly. The correct equivalent expression should have a combined x term of 6x, not 7x. This error highlights the importance of carefully simplifying expressions and ensuring that the resulting expression is equivalent to the original.
Discussion
This error can be attributed to a lack of attention to detail or a misunderstanding of the concept of equivalent expressions. It's essential to review and practice simplifying expressions to develop a strong understanding of this concept.
Recommendations
To avoid making similar errors, it's recommended to:
- Carefully read and understand the original expression
- Combine like terms correctly
- Verify that the resulting expression is equivalent to the original
- Review and practice simplifying expressions regularly
Introduction
In our previous article, we analyzed the equivalent expression written by Tyrone and identified the error he made. In this article, we'll provide a Q&A analysis to further understand the concept of equivalent expressions and how to avoid making similar errors.
Q&A Analysis
Q: What is an equivalent expression?
A: An equivalent expression is an expression that has the same value as another expression, but may be written in a different way.
Q: Why is it essential to simplify expressions?
A: Simplifying expressions is essential to ensure that the resulting expression is equivalent to the original. It also helps to make the expression more manageable and easier to work with.
Q: What are like terms?
A: Like terms are terms that have the same variable(s) raised to the same power. For example, 2x and 5x are like terms because they both have the variable x raised to the power of 1.
Q: How do I combine like terms?
A: To combine like terms, you need to add or subtract the coefficients of the like terms. For example, 2x + 5x = (2 + 5)x = 7x.
