What two numbers have a product of 92 and a sum of 47?




To find the answer to "What two numbers have a product of 92 and a sum of 47?" we first state what we know. We are looking for x and y and we know that x • y = 92 and x + y = 47.

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 = 47 and solve it for y to get y = 47 - x. Then, we replace y in x • y = 92 with 47 - x to get this:

x • (47 - x) = 92

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 92 and a sum of 47. The numbers are:

2.04656
44.95344


That's it! The two numbers that have a product of 92 and a sum of 47 are 2.04656 and 44.95344 as proven below:

2.04656 • 44.95344 ≈ 92

2.04656 + 44.95344 = 47

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