## Questions and Answers

### What is the general form of a linear equation?

$$ax + b = 0$$

### In a linear equation, if an item is sold at $25 each and the store makes a profit of$150, what would be the linear equation representing this situation?

$$25x - 150 = 0$$

### Which equation is an example of a quadratic equation?

$$7x^2 - x = 0$$

### Financial Planning and Algebra

Algebra underpins financial planning by allowing us to model and analyze financial situations through equations and inequalities. For instance, an investor could use algebra to understand the relationship between annual returns, compound interest, and the time it takes to reach their desired savings goal.

Algebraic concepts like solving systems of linear equations and graphing quadratic functions are vital in optimizing financial decisions, such as determining the best loan repayment strategy or calculating the monthly payments needed for a mortgage.

### Conclusion

In conclusion, algebra provides a language for understanding relationships between quantities in various contexts, such as time and distance in physical situations or interest and time in financial situations. By studying linear and quadratic equations, we gain a deeper understanding of the fundamental concepts that enable us to make informed decisions in our daily lives. Algebra's power lies in its ability to model and analyze complex real-world problems, leading to new insights and innovative solutions.
