To find the answer to "What two numbers have a product of 184 and a sum of 71?" we first state what we know. We are looking for x and y and we know that x • y = 184 and x + y = 71.
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 = 71 and solve it for y to get y = 71 - x. Then, we replace y in x • y = 184 with 71 - x to get this:
x • (71 - x) = 184
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 184 and a sum of 71. The numbers are:
2.69375
68.30625
That's it! The two numbers that have a product of 184 and a sum of 71 are 2.69375 and 68.30625 as proven below:
2.69375 • 68.30625 ≈ 184
2.69375 + 68.30625 = 71
Note: Answers are rounded up to the nearest five decimals if necessary so the answers may not be exact.
