At What Value Of $x$ Is $\frac{2}{3x-5}$ Undefined?
Introduction
In mathematics, a fraction is undefined when its denominator is equal to zero. This is because division by zero is not defined in mathematics. Therefore, to find the value of $x$ for which the given fraction is undefined, we need to find the value of $x$ that makes the denominator equal to zero.
The Denominator of the Fraction
The denominator of the given fraction is $3x-5$. To find the value of $x$ that makes the denominator equal to zero, we need to set the denominator equal to zero and solve for $x$.
Setting the Denominator Equal to Zero
We set the denominator equal to zero as follows:
Solving for $x$
To solve for $x$, we need to isolate $x$ on one side of the equation. We can do this by adding $5$ to both sides of the equation and then dividing both sides by $3$.
Conclusion
Therefore, the value of $x$ for which the given fraction is undefined is $\frac{5}{3}$.
Importance of Understanding Undefined Fractions
Understanding when a fraction is undefined is crucial in mathematics, especially in algebra and calculus. It helps us to avoid division by zero, which is not defined in mathematics. In addition, understanding undefined fractions is essential in solving equations and inequalities, as it helps us to identify the values of the variables that make the equation or inequality undefined.
Real-World Applications of Undefined Fractions
Undefined fractions have many real-world applications. For example, in physics, undefined fractions are used to describe the behavior of particles that are not observable. In engineering, undefined fractions are used to model complex systems that are not fully understood. In finance, undefined fractions are used to calculate the risk of investments.
Common Mistakes to Avoid
When working with fractions, it is easy to make mistakes. One common mistake is to forget to check if the denominator is equal to zero before dividing. Another common mistake is to assume that a fraction is defined when it is not. To avoid these mistakes, it is essential to understand when a fraction is undefined and to check the denominator before dividing.
Tips for Solving Undefined Fractions
Solving undefined fractions requires a deep understanding of algebra and calculus. Here are some tips for solving undefined fractions:
- Always check the denominator before dividing.
