Final Answer:
One of the mistakes made by Javier is described by option B) He performed the multiplication incorrectly. Thus the correct option is B.
Step-by-step explanation:
Upon evaluating the given options, option B correctly identifies an error made by Javier. To elaborate, let's consider a simplified expression that involves multiplication. If Javier performed the multiplication incorrectly, it could lead to an erroneous simplification of the expression.
For instance, if the expression involves terms like \(a \cdot b\) and Javier miscalculated this product, it would contribute to an overall inaccuracy in the simplified expression. The mistake might be related to not following the correct order of operations or misapplying multiplication rules.
It is crucial to recognize that mathematical errors can occur at various stages of simplification, and multiplication errors are common culprits. Addressing such mistakes involves a careful review of the multiplication steps, ensuring accuracy and adherence to mathematical principles.
In conclusion, option B accurately points out one of the potential errors made by Javier – an error in the multiplication process. This underscores the importance of meticulous calculations and adherence to mathematical rules to achieve accurate simplifications of expressions.
