To find the answer to "What two numbers have a product of 92 and a sum of 88?" we first state what we know. We are looking for x and y and we know that x • y = 92 and x + y = 88.
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 = 88 and solve it for y to get y = 88 - x. Then, we replace y in x • y = 92 with 88 - x to get this:
x • (88 - 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 88. The numbers are:
1.05818
86.94182
That's it! The two numbers that have a product of 92 and a sum of 88 are 1.05818 and 86.94182 as proven below:
1.05818 • 86.94182 ≈ 92
1.05818 + 86.94182 = 88
Note: Answers are rounded up to the nearest five decimals if necessary so the answers may not be exact.
