To find the answer to "What two numbers have a product of 44 and a sum of 23?" we first state what we know. We are looking for x and y and we know that x • y = 44 and x + y = 23.

Before we keep going, it is important to know that x • y is the same as y • x and x + y is the same as y + x. The two variables are interchangeable. Which means that when we create one equation to solve the problem, we will have two answers.

To solve the problem, we take x + y = 23 and solve it for y to get y = 23 - x. Then, we replace y in x • y = 44 with 23 - x to get this:

x • (23 - x) = 44

Like we said above, the x and y are interchangeable, therefore the x in the equation above could also be y. The bottom line is that when we solved the equation we got two answers which are the two numbers that have a product of 44 and a sum of 23. The numbers are:

2.10585

20.89415

That's it! The two numbers that have a product of 44 and a sum of 23 are 2.10585 and 20.89415 as proven below:

2.10585 • 20.89415 ≈ 44

2.10585 + 20.89415 = 23

Note: Answers are rounded up to the nearest five decimals if necessary so the answers may not be exact.
