# P Two Numbers Differ By 3 And Their Product Is 504: Find The Numbers P

In the world of mathematics, problem-solving often involves working with equations and variables. One common type of problem is finding two numbers when you know that they differ by a certain value and their product is a specific number. In this article, we will tackle a mathematical puzzle: “P Two Numbers Differ By 3 And Their Product Is 504: Find The Numbers P.” We will explore the algebraic approach to solve this problem step by step, ensuring that you understand the process completely.

## Understanding the Problem

To begin, let's break down the problem statement. We are given two key pieces of information:

1. The difference between the two numbers is 3.
2. The product of these two numbers is 504.

Our task is to find these two numbers, which we'll denote as P and Q.

## The Algebraic Approach

To solve this problem, we can set up a system of equations based on the information provided. Let's denote the two numbers as follows:

• P for the larger number.
• Q for the smaller number.

We can create the following equations based on the given information:

1. P – Q = 3 (since the numbers differ by 3)
2. P * Q = 504 (since the product of the numbers is 504)

## Factoring 504

Before we proceed with solving for P and Q, let's factor 504 to simplify our equations. Factoring 504 gives us the following prime factors:

• 2^3 * 3^2 * 7

Factoring is a process in which we break down a number into its prime factors, which are the building blocks of that number. In this case, 504 can be expressed as the product of 2 raised to the power of 3, 3 raised to the power of 2, and 7. This prime factorization helps us work with the number more easily.

## Solving for P

Now that we have factored 504, we can use this information to find the values of P and Q. We can set up the following equations based on the prime factors:

1. P – Q = 3
2. P * Q = 2^3 * 3^2 * 7

We can use these equations to solve for P and Q simultaneously. Let's break down the steps involved in solving for P:

Step 1: Solve for P – Q = 3 To isolate P in the first equation, we can add Q to both sides: P – Q + Q = 3 + Q

This simplifies to: P = 3 + Q

Step 2: Substitute P in the second equation Now that we have an expression for P, we can substitute it into the second equation:

(3 + Q) * Q = 2^3 * 3^2 * 7

Step 3: Solve for Q Multiply out the terms on the left side of the equation:

3Q + Q^2 = 2^3 * 3^2 * 7

This is a quadratic equation in terms of Q. We can rearrange it to the standard quadratic form:

Q^2 + 3Q – 2^3 * 3^2 * 7 = 0

Now, we can solve this quadratic equation for Q using the quadratic formula:

Q = (-B ± √(B^2 – 4AC)) / 2A

In this formula:

• A = 1
• B = 3
• C = -2^3 * 3^2 * 7

Plugging these values into the formula and performing the calculations, we get two possible solutions for Q: Q = 18 and Q = -21.

However, since we are looking for two numbers that differ by 3, we discard the negative solution (-21) as it doesn't make sense in this context. So, Q = 18.

Step 4: Find P Now that we have the value of Q, we can find P using the equation we derived earlier: P = 3 + Q P = 3 + 18 P = 21

So, the two numbers we were looking for are P = 21 and Q = 18.

## Verification of the Solution

To verify our solution, we can check if the values of P and Q satisfy both conditions:

1. P – Q = 3
2. P * Q = 504

Indeed, P – Q = 21 – 18 = 3, and P * Q = 21 * 18 = 504. Both conditions are met, confirming that our solution is correct.

## Conclusion

In conclusion, we've successfully solved the mathematical puzzle of finding two numbers, P and Q, which differ by 3 and have a product of 504. By using algebraic equations and factoring, we found that P = 21 and Q = 18. These numbers satisfy the given conditions. Mathematics is a powerful tool for problem-solving, and this example demonstrates its application in a real-world scenario.
