What two numbers have a product of 94 and a sum of -71?




To find the answer to "What two numbers have a product of 94 and a sum of -71?" we first state what we know. We are looking for x and y and we know that x • y = 94 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 = 94 with -71 - x to get this:

x • (-71 - x) = 94

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 94 and a sum of -71. The numbers are:

-69.6504
-1.3496


That's it! The two numbers that have a product of 94 and a sum of -71 are -69.6504 and -1.3496 as proven below:

-69.6504 • -1.3496 ≈ 94

-69.6504 + -1.3496 = -71

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